Read the following article and select the best answer. Article: The koala is one of Australia's most treasured creatures, which is a lovely little creature. But now, it is in big trouble. Affected by habitat loss and climate change, like many other uniquely Australian animals, koalas are being squeezed into smaller regions. But at present, it is a deadly disease, a somewhat silent killer that causes a further decline in the koala population, that is worrying many scientists about the fate of the koala. The killer is Chlamydia, which has caused symptoms in up to 50 percent of the wild koalas, with probably even more infected but not showing symptoms. It has been particularly severe in Queensland, where nearly all koalas are infected. The disease causes many symptoms including eye infections, which can lead to blindness, making it difficult for them to find their primary food. Treating Chlamydia in wild koalas is a challenge. There is no treatment available for _ . Only a small percentage of the animals can be treated successfully and returned to the wild. Besides, there is no national plan in Australia to save the koala;it is up to each region to make management plans for its koala population. The good news is that researchers are working to test a vaccine that would help prevent further spread. If all goes well, plans can be carried out to distribute the vaccil1e more widely. But it's impossible to vaccinate all wild koalas. Another possibility would be to make vaccine distribution a routi11e part of treatment for the thousands of koalas brought into care centers every year after they are injured by cars or dogs. While it is a combination of problems that are affecting the wild koala population, many experts believe this vaccine would be an important step in helping koalas survive longer. It may buy enough time to give researchers a chance to solve some of the other problems facing Australia's koalas. Question: Which isn't considered the main cause of koala's population decline? - Habitat loss. - Injuries from cars and dogs. - Climate change. - A deadly disease.
(Answer)
Injuries from cars and dogs.

Read the following article and select the best answer. Article: Mental and health experts believe personality plays an important part in how we experience stress. Personality is the way a person acts, feels and thinks. Some people are aggressive and always in a hurry. They often become angry when things do not happen the way they planned. They are called "Type A" personalities. Studies suggest that these people often get stress-related disorders. The "Type B" personality is calmer. These people are able to deal with all kinds of situations more easily. As a result, they are less affected by stress. Studies have also shown that men and women deal with stress differently. Women seem to be better able to deal with stress than men are. However, experts say women are three times more likely to develop depression in reaction to the stress in their lives. American writer John Gray became famous for his book, "Men are from Mars, Women are from Venus." He notes that men and women have opposite ways of dealing with stress. For a man, the best way is to rest and forget about daily problems. But a woman suffering from stress needs to talk about her problems. Experts say there are several ways to deal with stress, including deep breathing, exercise, eating healthy foods, getting enough rest and balancing the time spent working and playing. Exercise is one of the most effective stress-reduction measures, as physical changes from exercise make you feel better. In addition, exercise can also improve the body's defense system against disease. Keeping stress to yourself can make problems worse. Experts say that expressing emotions to friends or family members or writing down your feelings can help reduce stress. And they also suggest that people should attempt to accept or change stressful situations whenever possible. Question: Compared with "Type A" personalities, "Type B" personalities _ . - cause more troubles - are less able to cope with different situations - are more easily affected by stress - tend to solve problems more peacefully
(Answer)
tend to solve problems more peacefully

On Saturday, Anna threw a softball 16 feet and used a metal bat to hit a softball 15 feet off a tee . She threw a football more than 9 feet. She scored 10 points in "crazy water bocce ".
