In the summer of 1944, the popular comedian and radio personality Bob Hope began another of
his famous tours of military camps for the United Service Organizations (USO). This particular tour
made stops in Hawaii and on small islands all across the Pacific theater, where Hope and his troupe
performed 150 shows in two months. American military personnel loved the shows. Hope's jokes and
silly stunts made them laugh and took their minds away from the war for a few minutes. Entertainment
gave them something to fight for.
Military commanders in all wars throughout history have understood that morale is essential to a
force's willingness to fight and endure hardship. While good morale depends (1) ________ many things,
including good leadership, clear purposes and good food, entertainment played a crucial role in the

Identical twins go on separate vegan and meat diets to see difference they make to body
In 2021, a set of identical twins took part in an experiment that involved one going vegan
while the other consumed meat to see which of these two diets is (1) ________. The diets are
complete polar opposites, but which one is being (2) ________ to your body?
Well, explorers Hugo and Ross Turner decided to put the plant-based and omnivore diets to
the test to see which was better - with Hugo ditching meat and dairy and Ross sticking to a diet
that included meat, dairy and fish. The twins took part in the Kings College London study over a
12-week period (3) ________ the same number of calories each day as well as carrying out the same
gym training.
Hugo admitted that the switch to a plant-based diet hadn't been easy, but he eventually
ended up feeling more energetic. "I was on the vegan diet and it really does take a hit on your
body. I was now having to eat fruit and nuts and alternatives that didn't have any dairy in them -
and so that meant I was eating a lot more wholesome food, which meant that my sugar levels were
a lot satiated during the day. I felt like I had more energy."
On the other hand, Ross' meat-eating journey was a little different. As he said, his gym
performance was 'up and down a little bit more'. He added that on some days of the challenge he
felt 'very energetic' and on others he would have 'huge lulls'.
By the end of the 12-week study, the men found that the differences between the two diets
weren't very significant, after all.

(CNN) - A couple abandoned their baby at an airport check-in desk in Tel Aviv, Israel after
arriving without a ticket for the child. The pair, who have not been identified, were checking in for a
Ryanair flight from Ben Gurion International Airport to Brussels, Belgium on Tuesday with the
infant. It emerged that the baby did not have a ticket, and the couple headed off to board the flight -
leaving their child behind on the airline check-in counter.
"The matter was referred to police", a spokeswoman for Ryanair told CNN in an email. She
said: "These passengers traveling from Tel Aviv to Brussels presented at check-in without a
booking for their infant. They then proceeded to security leaving the infant behind at check-in. The
check-in agent at Ben Gurion Airport contacted Airport Security, who retrieved these passengers,
and this is now a matter for local police."
According to Ryanair's website, "infants can be included in a flight reservation during the
online booking process." When making plans to travel with an infant, a pop-up message appears
on the site stating that there is a €25 ($27) charge - or the local currency equivalent - for each
one-way flight the baby takes while sitting on an adult's lap. A seat must be paid for by separate
arrangement if the adults want the baby to travel in a car seat.
The Israeli Airport Authority confirmed the episode to CNN and said in a statement: "A couple
and an infant with Belgian passports arrived for a flight at Terminal 1 without a ticket for the baby.
The couple also arrived late for the flight, once the check-in for the flight was closed. The couple
left the infant seat with the baby and ran toward the security checks at Terminal 1 in an attempt to
reach the boarding gate for the flight."
A spokesman for Israel Police told CNN in a phone call that the matter appeared to have
been resolved by the time police arrived on the scene. He said: "The baby was with the parents
and there's no further investigation."

Why NASA spacesuits are white
What do Neil Armstrong, Ed White, and today's ISS (International Space Station) astronauts have in
common? They all wore a white spacesuit. And they're not alone. Beyond NASA, space programs in countries
like Russia and China also use white suits. Not the colors of the Russian flag or China's iconic yellow and red,
just white. That basic color has saved countless astronaut lives. NASA didn't always have white spacesuits.
Their very first manned spaceflight featured silver suits, but none of those astronauts actually explored the
vacuum of space. And that's the key because out there, spacesuits have to be highly reflective. And the best
color for that isn't silver, it's white.
Here on Earth, our atmosphere shields us from 77% of the sun's radiation. But astronauts in space don't
have that natural shield, which makes them vulnerable to blistering temperatures, severe sunburn, and even
cancer-causing cell damage. So to combat that, they wear white suits that reflect the sun's harmful radiation.
But those white EVA (extra-vehicular activity) suits aren't the only garment in an astronaut's closet. When
heading into space or coming home, NASA astronauts wear a bright orange suit because that loud orange
stands out against the blue ocean and sky and is perfect for attracting attention, so if there's a malfunction during
landing and astronauts have to abandon ship, so to speak, they need to be easy to spot for rescue crews.
That being said, times are changing. Nowadays we have more sophisticated ways of locating astronauts
in need of rescue, like GPS trackers and transponders, so space agencies are now free to get creative with their
color choices. NASA and other programs are already starting to use other colors like deep blue and mustard
yellow. And in the future, they could look a lot different because NASA is heading to Mars. It will be the longest
crewed space mission to date, taking as long as three years from start to finish, and during that time, astronauts
could suffer from boredom or depression. That's where colorful spacesuits could be useful.
