Part 8
The Siamese crocodiles are believed to be extinct in the wild. It is speculated that there are only about two hundred Siamese crocodiles left in the wilderness. Most of the Siamese crocodiles in the wild are in remote areas of Thailand and Cambodia. Unlike other species of crocodiles, the Siamese crocodiles are quite inoffensive. They are a low threat to humans. Unless they are being attacked first, they are not likely to attack you.
One of the reasons why crocodiles are endangered is the destruction of their habitat. Many swamp areas are converted into farming areas. Furthermore, crocodile’s skins are very valuable. Many of crocodiles were hunted for their skin and meat. Global warming also contributes to the cause of endangering crocodiles because the weather and climate play significant roles in determining the sex of the crocodiles. If the weather is 31.6 degrees Celsius, male crocodiles will be produced. Female crocodiles are produced at lower temperature. 
Different efforts have been made to save the Siamese crocodiles. Comparing to other endangered animals, it is easier to save them. Because they lay a lot of eggs, it is easy to breed them. Like other species of crocodiles, the sex of the Siamese crocodiles is determined by the temperature in the stage of development. 
Question 1: The Siamese crocodiles ______.
 A. became completely extinct years ago and none of them exist in the wilderness
 B. are always ready to attack anyone who gets near them
 C. can be found in remote areas of Thailand and Cambodia	
 D. are very dangerous because they are offensive
Question 2: The second paragraph is about ______.
 A. the reasons why the Siamese crocodiles have become extinct B. swamp areas in Thailand and Cambodia
 C. the causes of global warming	D. hunting the Siamese crocodiles for food

 A. Habitat destruction	B. Global warming	 C. Illegal hunting D. lack of food
Question 4: Which of the following sentence is NOT true?
 A. Temperature has an effect on determining the sex of the crocodiles 
 B. People can eat crocodiles’ meat.
 C. People hunt Siamese crocodiles for their skin.
 D. More female crocodiles are produced if the weather is more than 31.6 degrees Celsius. 
Question 5: We can learn from the last paragraph that _______.
 A. the Siamese crocodiles are being protected from extinction
 B. saving the Siamese crocodiles from extinction is the most difficult
 C. temperature doesn’t affect other species of crocodiles
 D. it’s hard to breed Siamese crocodiles because they don’t lay eggs
