Chinese divers surrounded by sharks
Jan 03, 2025
[1] Nine Chinese individuals, including seven tourists and
two diving instructors, went missing while diving in Palau
on December 26.
[2] Experienced diving instructor Liu Xin and another diving
guide took seven Chinese tourists to dive on December 26
around 9:30 am. As the dive was coming to an end, Liu
sent a signal to the surface. Typically, after seeing the
signal, the captain would slowly maneuver the boat to
follow the divers, allowing them to board once they floated
off. __________ when they surfaced, they could not locate
the boat.
[3] They couid only float in the sea for nearly three hours,
believing that someone would come to rescue them, but
the ocean current changed direction, and they were swept
by currents into an area between two islands. At that point,
a new threat emerged. The underwater terrain shifted, and
the most physically fit diver among the nine felt as if he had
stepped on something. Liu looked down and noticed that a
bull shark was circling around his feet, along with six other
sharks nearby.
[4] Liu swiftly assembled everyone to make themselves
appear larger as most wild animals typically target
creatures that are smaller and tend to avoid approaching
larger groups. Fortunately, with Liu and the entire team
huddled together, the sharks refrained from acting
aggressively, and they avoided any danger.
[5] By evening, they had gone nearly 11 hours without
food. To conserve their energy, they used their diving
masks to collect rainwater and drank it to stay hydrated.
After spending too much time in the water, they started to
feel cold, so they used their buoyancy devices to hold each
other to stay together and preserve warmth. And, to
prevent falling asleep and risking hypothermia, they took
turns calling out their numbers every 30 minutes to stay
alert.
[6] After drifting in the water for about 27 hours, a rescue
boat located the nine individuals.
[7] "Alli nine Chinese citizens who went missing while diving
in Palau have been rescued and are reported to be in
stable condition", the Chinese Embassy in the Federated
States of Micronesia said on Friday.
[8] Liu said that the key reasons for their safe return
included the selfless assistance from fellow travelers, the
favorable ocean currents that kept them in proximity to
their initial location, and, most importantly, the excellent
physical condition and positive attitude of the group.
"Throughout those 20-plus hours, we maintained a lighthearted atmosphere, chatting and laughing without any
complaints," Liu said.

Mark the option that completes the following sentence from
text II correctly: ___________, when they surfaced, they
could not locate the boat." (paragraph 2).

TEXT I
Read the text below and answer question.
Is peanut butter a good source of protein? Nutrition
experts explain.
[1] Protein is the macronutrient du jour. Discussions about
nutrition online as of late are all about making sure you're
consuming enough protein every day.
[2] The Recommended Dietary Allowance (RDA) for
protein is currently 0.36 grams of protein per pound,
according to Harvard Health, or about 54 grams daily for a
person who weighs 150 pounds.
[3] But diet experts are increasingly pushing for consuming
higher amounts of protein: upwards of 60 to 90 grams
daily. Registered dietitian Jamie Nadeau previously told
USA TODAY that she recommends getting "at least 20
grams of protein per meal for satiety," though she notes
everyone has different needs.
[4] To what extent can peanut butter help you reach those
goals? Nutrition experts explain.
[5] A two-tablespoon serving of peanut butter contains
about 7 grams of protein, according to the U.S.
Department of Agriculture's (USDA) food database.
[6] That doesn't mean you shouldn't eat peanut butter -
experts say it just means peanut butter is meant to be a
small part of more well-rounded meals. Thomason
suggests pairing a serving of peanut butter with a carb,
protein and a fruit or vegetable. Some favorite combos
include peanut butter and an apple, peanut butter and
banana toast and a smoothie or oatmeal with peanut
butter.
[7] "Those things are going to help you balance it out and
not feel like it's easy to overeat,"she says.
[8] To hit that recommended 20-gram goal, you'd have to
eat about 6 tablespoons - nearly three servings of peanut
butter - which amounts to nearly 600 calories. While
experts say eating more than the serving size isn't harmful,
per se, there are much easier (and less calorie-dense)
food options to get more protein.
(Adapted from https://www.usatoday.com)
The pronoun "it" in the sentence "Those things are going to
help you balance it out and not feel like it's easy to overeat,
[...]" (paragraph 7) refers to:

ChatGPT May Be Eroding Critical Thinking Skills, According to a New MIT Study
By Andrew R. Chow
The study divided 54 subjects — 18 to 39 year-olds from the Boston area — into three groups, and asked them to
write several SAT essays using OpenAl's ChatGPT, Google’s search engine, and nothing at all, respectively. Researchers used an (electroencephalogram) EEG to record the writers’ brain activity across 32 regions, and found that of the
three groups, ChatGPT users had the lowest brain engagement and “consistently underperformed at neural, linguistic,
and behavioral levels.” Over the course of several months, ChatGPT users got lazier with each subsequent essay, often
resorting to copy-and-paste by the end of the study.
The paper suggests that the usage of (Large Language Model) LLMs could actually harm learning, especially for
younger users. The paper has not yet been peer reviewed, and its sample size is relatively small. But its paper’s main
author Nataliya Kosmyna felt it was important to release the findings to elevate concerns that as society increasingly
relies upon LLMs for immediate convenience, long-term brain development may be sacrificed in the process.
The group that wrote essays using ChatGPT all delivered extremely similar essays that lacked original thought,
relying on the same expressions and ideas. Two English teachers who assessed the essays called them largely
“soulless” The EEGs revealed low executive control and attentional engagement. And by their third essay, many of
the writers simply gave the prompt to ChatGPT and had it do almost all of the work. “It was more like, ‘just give me the
essay, refine this sentence, edit it, and 'm done,” Kosmyna says.
The brain-only group, conversely, showed the highest neural connectivity, especially in alpha, theta and delta bands,
which are associated with creativity ideation, memory load, and semantic processing. Researchers found this group
was more engaged and curious, and claimed ownership and expressed higher satisfaction with their essays.
The third group, which used Google Search, also expressed high satisfaction and active brain function. The
difference here is notable because many people now search for information within Al chatbots as opposed to Google
Search.
After writing the three essays, the subjects were then asked to re-write one of their previous efforts—but the
ChatGPT group had to do so without the tool, while the brain-only group could now use ChatGPT. The first group
remembered little of their own essays, and showed weaker alpha and theta brain waves, which likely reflected a
bypassing of deep memory processes.
The second group, in contrast, performed well, exhibiting a significant increase in brain connectivity across all EEG
frequency bands. This gives rise to the hope that Al, if used properly, could enhance learning as opposed to diminishing it.

Why did the researchers mention the small sample size?

ChatGPT group had to do so without the tool, while the brain-only group could now use ChatGPT. The first group
remembered little of their own essays, and showed weaker alpha and theta brain waves, which likely reflected a
bypassing of deep memory processes.
The second group, in contrast, performed well, exhibiting a significant increase in brain connectivity across all EEG
frequency bands. This gives rise to the hope that Al, if used properly, could enhance learning as opposed to diminishing it.

ChatGPT May Be Eroding Critical Thinking Skills, According to a New MIT Study
By Andrew R. Chow
The study divided 54 subjects — 18 to 39 year-olds from the Boston area — into three groups, and asked them to
write several SAT essays using OpenAl's ChatGPT, Google’s search engine, and nothing at all, respectively. Researchers used an (electroencephalogram) EEG to record the writers’ brain activity across 32 regions, and found that of the
three groups, ChatGPT users had the lowest brain engagement and “consistently underperformed at neural, linguistic,
and behavioral levels.” Over the course of several months, ChatGPT users got lazier with each subsequent essay, often
resorting to copy-and-paste by the end of the study.
The paper suggests that the usage of (Large Language Model) LLMs could actually harm learning, especially for
younger users. The paper has not yet been peer reviewed, and its sample size is relatively small. But its paper’s main
author Nataliya Kosmyna felt it was important to release the findings to elevate concerns that as society increasingly
relies upon LLMs for immediate convenience, long-term brain development may be sacrificed in the process.
The group that wrote essays using ChatGPT all delivered extremely similar essays that lacked original thought,
relying on the same expressions and ideas. Two English teachers who assessed the essays called them largely
“soulless” The EEGs revealed low executive control and attentional engagement. And by their third essay, many of
the writers simply gave the prompt to ChatGPT and had it do almost all of the work. “It was more like, ‘just give me the
essay, refine this sentence, edit it, and 'm done,” Kosmyna says.
The brain-only group, conversely, showed the highest neural connectivity, especially in alpha, theta and delta bands,
which are associated with creativity ideation, memory load, and semantic processing. Researchers found this group
was more engaged and curious, and claimed ownership and expressed higher satisfaction with their essays.
The third group, which used Google Search, also expressed high satisfaction and active brain function. The
difference here is notable because many people now search for information within Al chatbots as opposed to Google
Search.

Read the text about a military briefing and choose the false statement.
Now the platoon commander of No 3 Platoon is briefing his section commanders:
‘Pay attention and take notes. The Company Commander is not happy with the standard of map reading. So, next Tuesday, 26th October, the whole platoon is going out on a 24-hour exercise, Exercise "Hot Foot". The aim of the exercise is to give the platoon practice in compass marching across country. You will move by day and night. The dress for the exercise will be fighting order. You will not carry weapons and ammunition. You are to draw combat rations for your sections from the stores. Do this at 1600 hours on Monday 25th October. Individuals will be responsible for their own meals during the exercise. Each man is to take a protractor, a compass, map sheet 175, map-case, torch and chinagraph pencils. You are responsible for checking this. The platoon is to parade outside the guardroom at 0730 hours on Tuesday 26th October. We shall travel to the exercise area by 4-tonner but we shall march back to camp. Estimated time of return to camp will be 1030 hours on Wednesday 27th October. Make sure you brief your sections. Right, that's all. Any questions?’

Read the text about soccer in Brazil and choose the false statement.
Soccer is the national sport of Brazil. The Brazilian passion for the game leads many observers to describe it as more of a religion than a sport for Brazilians. Intense and often fanatical support of the national team is a force that serves to bridge Brazil's ethnic and class divisions. Its national team is the only team that has played in all nineteen World Cup competitions, the sport's highest level of international play that are held every four years. Brazil is also the only team to win the tournament five times. Males of all classes and backgrounds play soccer. Its popularity stems partly from its limited equipment demands. The poorest of youth play in the streets because soccer requires just a ball (or even a makeshift ball) and some open space. Peladas, or pick-up games, are common occurrences, especially on Sundays. For spectators, national team games draw the attention of the entire nation. Work essentially halts while Brazilians gather to watch the game in homes, offices, bars, and other venues. Wins in international competition can lead to nationwide partying and parades; losses can lead to widespread disappointment and national debate concerning the team's performance and future.

TITLE: Asteroid probe snaps rare images of Martian Moon
March 13, 2025 3:29 PM
By Agence France-Press
Paris -
On the way to investigate the scene of a historic asteroid
collision, a European spacecraft swung by Mars and
captured rare images of the red planet's mysterious small
moon Deimos, the European Space Agency said
Thursday.
Europe's HERA mission is aiming to find out how much of
an impact a NASA spacecraft made when it deliberately
smashed into an asteroid in 2022 in the first test of our
planetary defenses.
But HERA will not reach the asteroid - which is 11 million
kilometers from Earth in the asteroid belt between Mars
and Jupiter - until late 2026.
On the long voyage there, the spacecraft swung around
Mars on Wednesday.
The spacecraft used the planet's gravity to get a "kick" that
also changed its direction and saved fuel, mission analyst
Pablo Munoz told a press conference.
For an hour, HERA flew as close as 5,600 kilometers from
the Martian surface, at a speed of 33,480 kilometers an
hour.
It used the opportunity to test some of its scientific
instruments, snapping around 600 pictures, including rare
ones of Deimos.
The lumpy, 12.5-kilometer-wide moon is the smaller and
less well-known of the two moons of Mars.
Exactly how Deimos and the bigger Phobos were formed
remains a matter of debate.
Some scientists believe they were once asteroids that
were captured in the gravity of Mars, while others think they could have been shot from a massive impact on the
surface.
The new images add "another piece of the puzzle" to
efforts to determine their origin, Marcel Popescu of the
Astronomical Institute of the Romanian Academy said.
There are hopes that data from HERA's "HyperScout" and
thermal infrared imagers which observe colors beyond
the limits of the human eye - will shed light on this mystery
by discovering more about the moon's composition.
Those infrared imagers are why the red planet appears
blue in some of the photos.
Next, HERA will turn its focus back to asteroid Dimorphos.
When NASA's DART mission smashed into Dimorphos in
2022, it shortened the 160-meter-wide asteroid's orbit
around its big brother Didymos by 33 minutes.
Although Dimorphos itself posed no threat to Earth, HERA
intends to discover whether this technique could be an
effective way for Earth to defend itself against possibly
existence-threatening asteroids in the future.
Space agencies have been working to ramp up Earth's
planetary defences, monitoring for potential threats so they
can be dealt with as soon as possible.
Earlier this year, a newly discovered asteroid capable of
destroying a city was briefly given a more than 3% chance
of hitting Earth in 2032.
However further observations sent the chances of a direct
hit back down to nearly zero.
Richard Moissl, head of the ESA's planetary defense
office, said that asteroid, 2024 YR, followed a pattern that
will become more common.
As we get better at scanning the skies, "we will discover
asteroids at a higher rate," he said.
The ESA is developing a secondary planetary defense
mission to observe the 350-meter-wide asteroid Apophis,
which will fly just 32,000 kilometers from Earth on April 13,
2029.
If approved by the ESA's ministerial council, the Ramses
mission will launch in 2028, reaching the asteroid two
months before it approaches Earth.

The world's strongest ocean current should be getting
faster - instead, it is at risk of failing.
Antarctica's remote and mysterious current has a profounp
influence on the climate, food systems and Antarctic
ecosystems. Can we stop it weakening by 2050? The
Antarctic Circumpolar Current is the strongest ocean
current on the planet. It's five times stronger than the Gulf
Stream and more than 100 times stronger than the
Amazon River. It forms part of the global ocean "conveyor
belt" connecting the Pacific, Atlantic and Indian oceans.
The system regulates Earth's climate and pumps water,
heat and nutrients around the globe. But fresh, cool water
from melting Antarctic ice is diluting the salty water of the
ocean, potentially disrupting the vital ocean current.
The Antarctic Circumpolar Current is like a moat around
the icy continent. The current helps to keep warm water at
bay, protecting vulnerable ice sheets. It also acts as a
barrier to invasive species such as southern bull kelp and
any animals hitching a ride on these rafts, spreading them
out as they drift towards the continent. It also plays a big
part in regulating the Earth's climate.
The influence of climate change:
Ocean currents respond to changes in temperature, salt
levels, wind patterns and sea ice extent. So the global
ocean conveyor belt is vulnerable to climate change on
multiple fronts. Previous research suggested one vital part
of this conveyor belt could be headed for a catastrophic
collapse. Theoretically, warming water around Antarctica
should speed up the current. This is because density
changes and winds around Antarctica dictate the strength
of the current. Warm water is less dense (or heavy) and
this should be enough to speed up the current.
Far-reaching consequences:
The consequences of a weaker Antarctic Circumpolar
Current are profound and far-reaching. As the main current
that circulates nutrient-rich waters around Antarctica, it
plays a crucial role in the Antarctic ecosystem. Weakening
of the current could reduce biodiversity and decrease the
productivity of fisheries that many coastal communities rely
on. It could also aid the entry of invasive species such as
southern bull kelp to Antarctica, disrupting local
ecosystems and food webs.
