READ THE PASSAGE AND ANSWER THE QUESTIONS THAT FOLLOW.

Six tons of pure power whacks an ice floe floating in cold Arctic waters. The seal lying on top of the ice doesn't stand a chance. Knocked into the sea, the seal becomes a meal for one of the ocean's top predators–the huge orca, or killer whale.
Orcas hunt everything from fish to walruses, seals, sea lions, penguins, squid, sea turtles, sharks, and even other kinds of whales. Depending on the season and where they are, their diet varies - some orcas eat more fishes and squid than seals and penguins. But wherever they are in any of the world's oceans, average-sized orcas may eat about 500 pounds (227 kilograms) of food a day. Orcas have many hunting techniques, and bumping seals off ice is just one of them.
Often referred to as wolves of the sea, orcas live and hunt together in cooperative pods, or family groups, much like a pack of wolves. They work together as they hunt. Groups of orcas cooperate to herd fish into a compact area so that they're easier to eat. They will also slap their tails onto the water's surface, causing a wave to wash prey, such as penguins or sea lions, off ice floes and into the water. Sometimes, a pod of whales will join forces to surround a larger animal, such as a blue whale. They chase, bite, and wear it down until it becomes a meal.
Orcas' teeth, numbering about 45 and each measuring about 3 inches (7.6 centimetres) long, are shaped for ripping and tearing prey. Orcas do not chew their food. They can swallow small seals and sea lions whole. The prey easily slides down the orcas' throats. Bigger prey is eaten in chunks. Ocras' backs are black and their stomachs are white. Animals looking down on an orca from above, such as a seal on an ice floe, might not see it because the whale's dark back blends with the water below. On the other hand, the whale's white underside blends with the light streaming down into the sea from the surface, making it hard to be spotted from below. The colour pattern of orcas help them sneak up on their prey and attack them. With orcas camouflaged so well, those prey fish, penguins or seals are likely to miss the danger heading their way, as the killer whale once again proves it is the oceans' superbly designed hunter.

How is it possible for orcas to camouflage in the sea water?

A Their dark back and white underside hide them well from their preys above and below the water.
B The orcas like to chase, bite and wear their preys down.
C They have many hunting techniques.
D They are the ultimate killing machine; they do not need to camouflage.

Read the passage and answer the question that Follow.

Most people would shudder at the idea of getting caught up in a 73.5-feet wave. But for Brazilian pro-surfer Maya, it presented the perfect opportunity to break her 2018 world record for the largest wave surfed by a female. The athlete skillfully conquered the massive wave earlier this year, at the inaugural World Surf League (WSL) Nazaré Tow Surfing Challenge in Praia do Norte, Portugal. It was the same site where she made her first world record by riding an equally intimidating 68-feet wave.
"I was in the zone and braver than I usually am on that day," said Gabeira. "I was risking more than I usually like to do. When I let go of the rope, I had a feeling it could be the one but wasn't sure. The speed was very high, but the noise that the wave made when it broke made me realize that this was probably the biggest wave I'd ever ridden."
Though Gabeira completed the incredible feat on February 11, 2020, her record was not announced by the Guinness World Records until September 10, 2020. That's because the WSL officials had to first determine whether it was the Brazilian surfer or her competitor, Justine Dupont, who had ridden the largest wave. The wave's height from trough to crest is usually estimated with the help of photos and videos. However, the proximity of the large swells ridden by the two pro-surfers, and the possibility of a new world record being established, warranted a more rigorous analysis.


The first record was made by Gabeira on/in _______.

Aa 73.5 feet wave
B2018
C2020
D2010


what ????????????????? there wasn't even 2018 mentioned in passage
