Some years ago industries had more freedom than they have now, and they did not need to be as careful as they must today. They did not need to worry a lot about the safety of the new products that they developed. They did not have to pay much attention to the health and safety of the people who worked for them. Often new products were dangerous for the people who used them; often conditions in the work place had very bad effects on the health of the workers.
Of course sometimes there were real disasters which attracted the attention of governments and which showed need for changes. Also scientists who were doing research into the health of workers sometimes produced information which governments could not ignore. At such times, there were inquiries into the causes of the disaster or the problems. New safety rules were often introduced as a result of these inquiries; however, the new rule; came too late to protect the people who died or who became seriously iii.
Today many governments have special departments which protect customers and workers. In the U. S., for example, there is a department which tests new airplanes and gives warnings about possible problems. It also makes the rules that aircraft producers must follow. Another department controls the foods and drugs that companies sell. A third department looks at the places where people work, and then reports any companies that are breaking laws which protect the health and safety of workers. Of course, new government departments and new laws cannot prevent every accident or illness, but they are having some good results. Our work places are safer and cleaner than before. The planes and Cars which we use for travel are better. Producers are thinking more about the safety and health of the people who buy and use their products.

A:governments and companies had different opinions about the safety of products B:governments paid little attention to the safety of products C:government officials often did not listen to scientists D:in the past no safety laws were introduced by governments

Maybe ten-year-old Elizabeth put it best when she said to her father, "But, Dad, you can’t be healthy if you’re dead."
Dad, in a hurry to get home before dark so he could go for a run, had forgotten to wear his safety belt—a mistake 75% of the US population make every day. The big question is why.
There have been many myths about safety belts ever since their first appearance in cars some forty years ago. The following are three of the most common.
Myth Number One: It’s best to be "thrown clear" of a serious accident.
Truth: Sorry, but any accident serious enough to "throw you clear" is also going to be serious enough to give you a very bad landing. And chances are you’ll have traveled through a windshield (挡风玻璃) or door to do it. Studies show, that chances of dying after a car accident are twenty-five times greater in cases where people are "thrown clear."
Myth Number Two: Safety belts "trap" people in cars that are burning or sinking in water.
Truth: Sorry, again, but studies show that people knocked unconscious (昏迷) due to not wearing safety belts have a greater chance of dying in these accidents. People wearing safety belts are usually protected to the point of having a clear head to free themselves from such dangerous situation, not to be trapped in them.
Myth Number Three: Safety belts aren’t needed at speeds of less than 30 miles per hour (mph).
Truth: When two cars traveling at 30 mph hit each other, an unbelted driver would meet the windshield with a force equal to diving headfirst into the ground from a height of 10 meters.
What is the advice given in the text

A:Never drive faster than 30 miles an hour. B:Try your best to save yourself in a car accident. C:Never forget to wear the safety belt while driving. D:Drive slowly while you’re not wearing a safety belt.
