Read the following passage and choose the correct answer to each of the questions.

The scarcity of tigers and African elephants is more and more serious. They are endangered because poachers hunt them to sell tiger pelts and elephant ivory.

At least 4,000 elephants are killed each year to meet the global demand for ivory, which is used to make carvings, jewelry, and other products although it is illegal to sell ivory since 1989 anywhere.

A Wildlife Fund report states that the United States seized 8,300 illegal ivory items between 1995 and 2002. Each week there are about 1,000 ivory auctions, the report said.

As for tigers, their parts are used in traditional Chinese medicine. Tiger bones are used as a pain reliever in traditional medicine. Even tiger's whiskers are sold because some people in Asia think they are a good-luck charm – like a rabbit's foot in the United States. “Part of our job is education,” said Professor Dillon. “The other part is law enforcement. So we have more than one strategy.”
