Reading Comprehension


Modern supermarkets


Many of the major supermarket chains have come under fire with accusations of various unethical acts over the past decade. They’ve wasted loads of food, they’ve underpaid their suppliers and they’ve contributed to excessive plastic waste in their packaging, which has had its impact on our environment.


But supermarkets and grocers are starting to sit up and take notice. In response to growing consumer backlash against the huge amounts of plastic waste generated by plastic packaging, some of the largest UK supermarkets have signed up to a pact promising to transform packaging and cut plastic wastage. In a pledge to reuse, recycle or compost all plastic wastage by 2025, supermarkets are now beginning to take some responsibility for the part they play in contributing to the damage to our environment, with one major supermarket announcing their plan to eliminate all plastic packaging in their own-brand products by 2023.


In response to criticisms over food waste, some supermarkets are donating some of their food surplus. However, charities estimate that they are only accessing two per cent of supermarkets’ total food surplus, so this hardly seems to be solving the problem. Some say that supermarkets are simply not doing enough. Most supermarkets operate under a veil of secrecy when asked for exact figures of food wastage, and without more transparency it is hard to come up with a systematic approach to avoiding waste and to redistributing surplus food.


Some smaller companies are now taking matters into their own hands and offering consumers a greener, more environmentally friendly option. Shops like Berlin’s Original Unverpakt and London’s Bulk Market are plastic-free shops that have opened in recent years, encouraging customers to use their own containers or compostable bags. Online grocer Farmdrop eliminates the need for large warehouses and the risk of huge food surplus by delivering fresh produce from local farmers to its customers on a daily basis via electric cars, offering farmers the lion’s share of the retail price.


There is no doubt that we still have a long way to go in reducing food waste and plastic waste. But perhaps the major supermarkets might take inspiration from these smaller grocers and gradually move towards a more sustainable future for us all.


(adapted from www.britishcouncil.org)

Read the following paragraph about supermarkets:
Two of the things that major supermarkets have been ................................ for are the waste of large amounts of excess food and unnecessary plastic usage in a lot of product packaging. Some supermarkets have ................................ to try and reduce plastic wastage, and one supermarket has said that it would get ................................ of all plastic packaging from its own in-house brands. Meanwhile, many supermarkets are not very transparent about the exact amount of food that is going to waste and so it’s hard for charities to know how to redistribute this surplus .................................

Artificial Intelligence: The “lethal trifecta”

    LARGE LANGUAGE MODELS (LLMs), a trendy way of building artificial intelligence, have an inherent security problem: they cannot separate code from data. As a result, they are at risk of a type of attack called a prompt injection, in which they are tricked into following commands they should not. Sometimes the result is merely embarrassing, as when a customer-help agent is persuaded to talk like a pirate. On other occasions, it is far more damaging.

    The worst effects of this flaw are reserved for those who create what is known as the “lethal trifecta”. If a company, eager to offer a powerful AI assistant to its employees, gives an LLM access to untrusted data, the ability to read valuable secrets and the ability to communicate with the outside world at the same time, then trouble is sure to follow. And avoiding this is not just a matter for AI engineers. Ordinary users, too, need to learn how to use AI safely, because installing the wrong combination of apps can generate the trifecta accidentally. 

   Better AI engineering is, though, the first line of defence. And that means AI engineers need to start thinking like engineers, who build things like bridges and therefore know that shoddy work costs lives.

  The great works of Victorian England were erected by engineers who could not be sure of the properties of the materials they were using. In particular, whether by incompetence or malfeasance, the iron of the period was often not up to snuff. As a consequence, engineers erred on the side of caution, overbuilding to incorporate redundancy into their creations. The result was a series of centuries-spanning masterpieces.

   AI-security providers do not think like this. Conventional coding is a deterministic practice. Security vulnerabilities are seen as errors to be fixed, and when fixed, they go away. AI engineers, inculcated in this way of thinking from their schooldays, therefore often act as if problems can be solved just with more training data and more astute system prompts.

   These do, indeed, reduce risk. The cleverest frontier models are better at spotting and refusing malicious requests than their older or smaller cousins. But they cannot eliminate risk altogether. Unlike most software, LLMs are probabilistic. Their output is driven by random selection from likely responses. A deterministic approach to safety is thus inadequate. A better way forward is to copy engineers in the physical world and learn to work with, rather than against, capricious systems that can never be guaranteed to function as they should. That means becoming happier dealing with unpredictability by introducing safety margins, risk tolerance and error rates.

   Overbuilding in the AI age might, for instance, mean using a more powerful model than is needed for the task at hand, to reduce the risk it will be tricked into doing something inappropriate. It might mean imposing limits on the number of queries LLMs can take from external sources, calibrated to the risk of damage from a malicious query. And mechanical engineering emphasises failing safely. If an AI system must have access to secrets, then avoid handing it the keys to the kingdom.

   In the physical world, bridges have weight limits – even if they are not always stated clearly to drivers. And, importantly, these are well within the actual tolerances that calculations suggest a bridge will bear. The time has now come for the virtual world of AI systems to be similarly equipped.

Plan to test Liberian schoolchildren for drugs blocked

October 17th, 2025

By Moses Kollie Garzeawu

Monrovia, Liberia, Africa


Liberia's Education Ministry has blocked controversial plans to introduce mandatory drug testing in all of the country's schools.


Speaking to local media, the interim head of the Liberia Drug Enforcement Agency (LDEA), Fitzgerald Biago, said school testing would help address the growing problem of drug abuse.


The announcement sparked a mixed response. Some thought it would help tackle the scourge of drugs, while others saw it as an invasion of privacy, or feared it would cost too much.


Last year, President Joseph Boakai declared drug and substance abuse a national emergency and a recent EU-backed report estimated that one in five young Liberians take drugs.


However, the Education Ministry said it was not aware of any plans to test students and added that such a decision needed to be based on concrete evidence and properly thought through.


Assistant minister in charge of students Sona Toure-Sesay told the BBC that this kind of plan required proper research. "Let's assume we are made aware of the proposed initiatives by the LDEA, it will require us to conduct research and review case studies from other countries where this has been successful," she said.  


Toure-Sesay also noted that testing could affect students. "What happens to students who test positive? What are the social services in place for them? Some of them might be bullied even after returning, and it may affect their overall educational performances."


She added that a multi-sectoral committee on drug and substance abuse had been set up, headed by the Health Ministry. Along with strengthening health clubs in schools, she said that this would help to reduce the prevalence of drugs among students.


President Boakai dismissed the leadership of the LDEA in August this year, and recently appointed Biago, a former senior police officer, as interim head of the agency.

Text 1


Reading is not only about recognizing words — it’s about understanding, questioning, and connecting ideas. Strategic readers use different techniques to make sense of what they read. Before reading, they look at titles, subtitles, and pictures to predict what the text might be about. This helps them activate their background knowledge and prepare for new information.

While reading, good readers identify key words, take notes, and make inferences — that is, they read between the lines. They also stop to check if they really understand the text, and they don’t hesitate to reread a paragraph if something isn’t clear. Scanning and skimming are two important strategies: “scanning” is used to find specific information, like dates or names, and “skimming” is reading quickly to get the general idea.

After reading, strategic readers summarize the main ideas and reflect on what they have learned. They may also discuss the text with others, compare it with different opinions, or relate it to real-life experiences. In this way, reading becomes more meaningful and enjoyable. Being a strategic reader means being an active thinker who learns from every text.

The cardiovascular system provides blood supply throughout the body. Responding to various stimuli can control the velocity and amount of blood carried through the vessels. The cardiovascular system comprises the heart, arteries, veins, and capillaries. The heart and vessels work intricately to provide adequate blood flow to all body parts. The regulation of the cardiovascular system occurs via a myriad of stimuli, including changing blood volume, hormones, electrolytes, osmolarity, medications, adrenal glands, kidneys, and much more.

New Study: This Regional Accent Is Considered the Most Trustworthy in the U.S.—And the Results Will Really Surprise You!

By Jennifer Geddes

A person’s cadence counts for a lot.

Everyone knows first impressions are important— and we don’t just make them based on sight. Beyond a chic outfit and well-coiffed hair, how a person sounds can also be a big factor when forming an initial opinion. In fact, a recent analysis of more than a dozen American accents conducted by BetUS Casino found that some folks’ speech actually conveys more honesty and reliability than others’.

At this point, you’re probably praying your own voice sounds dependable, not shifty or shady, right? Try to relax, and then read on to learn (nay, hear!) where the most trustworthy accents are located.

How was the study conducted?

As with many studies today, internet data helped determine which parts of the country sound the most steadfast and true. BetUS Casino crafted the report, which is current as of Aug. 15, 2025, by focusing on how people feel about 14 different regional accents.

How did the company determine those feelings?

First, researchers looked at internet search terms like “friendly (accent)” or “professional (accent).” Then, to complete the rankings, they compiled data on the rate of financial crimes per 10,000 people, plus the number of lawyers and primary-care doctors in each area.

Why doctors and lawyers, you may ask? Well, these are professions that rely on trust—after all, you might have to put your life in their hands! The more of these professionals in an area, the more trustworthy the accent. Once the study authors had the information in hand, they weighted the data and ranked the regions on a scale of 1–100.

Which regional accent is considered the most trustworthy?

Now hear this: The regional accent that’s considered to be the most trustworthy hails from Boston!

Yup, the fine citizens of Beantown scored 56.1, which was enough to take top honors for sounding highly dependable. Boston ranks so strongly thanks to more than 23,300 searches related to how kind and upstanding the accent sounds. The Massachusetts capital and largest city in New England also sports a low level of financial crime and is home to tens of thousands of lawyers and doctors.

Boston shines in other ways too, underlining the trust factor essential to its distinctive accent. For example, one recent WalletHub report list Boston as the third most caring city in the nation, while another names Massachusetts as the best U.S. state to live in. And the Bay State has excellent health care, with the highest childhood vaccination rates, lowest infant mortality and fewest premature avoidable deaths.

Want to sound just like a Bostonian? Start by dropping some of your R’s, as in “pahk the cah” and “wicked smaht.” Or listen to Ben Affleck turn on the telltale accent in his Dunkin’ commercials. Other famous Bostonians with perfect inflection include Matt Damon, Mark Wahlberg and Amy Poehler.
