1. Read the passage carefully and choose the correct answer.

Every year, 100 million sharks are killed by people in commercial and recreational fishing. In the past they were killed simply for the sport of landing a good fighting fish (make sharks for instance). Sharkskin was used for making sandpaper. Other sharks are hunted for food, and some species for other products.

Sharks are a common seafood in many places around the world, in­cluding Japan and Australia. In Australia shark is the most commonly used fish. Sharks are often killed for shark fin soup, in which many sharks are hunted for their fins, which are cut off with a hot metal blade before the live animal is tossed back into the water. There have been cases where hundreds of de-finned animals were swept up on local beaches without any way to convey themselves back into the sea. Conservation­ists have campaigned for changes in the law to make finning illegal in the U.S.

Sharks generally reach sexual maturity slowly and produce very few offspring in comparison to other fishes that are harvested. This has caused concern among biologists regarding the increase in effort applied to catching sharks over time, and many species are considered to be threatened. Some organizations, such as the Shark Trust, campaign to limit shark fishing.
