Read the following article and select the best answer. Article: Most people around the world are right-handed. This also seems to be true in history. In 1799, scientists studied works of art made at different times from 1,500 B.C. to the 1950s. Most of the people shown in these works are right-handed, so the scientists guessed that right-handedness has always been common through history. Today, only about 10% to 15% of the world's population is left-handed. Why are there more right-handed people than left-handed ones? Scientists now know that a person's two hands each have their own jobs. For most people, the hand is used to find things or hold things. The right hand is used to work with things. This is because of the different work of the two sides of the brain. The right side of the brain, which makes a person's hands and eyes work together, controls the left hand. The left-side of the brain, which controls the right hand, is the centre for thinking and doing problems. These findings show that more artists should be left-handed, and studies have found that left-handedness is twice as common among artists as among people in other jobs. No one really knows what makes a person become right-handed instead of left-handed. Scientists have found that almost 40% of the people become left-handed because their main brain is damaged when they are born. However, this doesn't happen to everyone, so scientists guess there must be another reason why people become left-handed. One idea is that people usually get right-handed from their parents. If a person does not receive the gene for right-handedness, he / she may become either right-handed or left-handed according to the chance and the people they work or live with. Though right-handedness is more common than left-handedness, people no longer think left-handed people are strange or unusual. A long time ago, left-handed children were made to use their right hands like other children, but today they don't have to. Question: What is the hand for most people used to do? - It's used to find or hold things. - It's used to work with things. - It's used to make a person's eyes work together. - It's the centre for thinking and doing problems.
It's used to find or hold things.

Read the following article and select the best answer. Article: Deadly heat waves, home-wrecking hurricanes, neighborhood-burning wildfires...When you stop to think about it, global warming can be thoroughly depressing. According to rising evidence, climate changewon't just cause new cases of stress, anxiety and depression. People who already have serious psychological problems will probably suffer most in the result of natural disasters and extreme weather events. "When these events happen, people with pre-established mental illnesses often have more extreme difficulty," said Lisa Page, a psychiatrist. "This is an area we maybe need to think about a little more seriously." In public health circles and even in climate talks, scientists have studied how climate change might affect physical health, by for example, causing the spread of malaria, fever and other infectious diseases. For the most part, though, the experts have made only vague references to the link between climate change and mental health, even though evidence for such connections is starting to pile up. In the future, climate models predict more destructive storms, floods, droughts and diseases. In turn, the new study suggests, more psychological crises will follow. Heat waves -- like the one that killed some 70,000 people in Europe in the summer of 2003 -- will also happen more frequently, last longer and be severer in coming years. The mentally ill will be hardest hit by these events because they're more likely to live in poor housing without air conditioning. People with pre-existing mental challenges will probably also have an extra hard time dealing with other forecasted consequences of climate change, including the sinking of coastlines and mass migration away from flooded shores. Then, there's the general sense of sadness that can come from reading about climate change, and recognizing that the world is changing. Question: We can know from the text _ . - when people read about climate change, they are sure the world will be destructive - heat waves in Europe will happen again in the near future - the experts haven't clearly found out the relationship between climate change and mental health - malaria, fever and other infectious diseases are caused by climate change
(Answer)
the experts haven't clearly found out the relationship between climate change and mental health
