【正文】 al safety standards ISO11540, except for in cases where the cap is considered too large to be a choking risk. That39。s rather lovely of them. In appreciation of their want to not kill off their more clumsy customers, we thought we39。d share a few more random facts about Bic that are probably going to e up in a pub quiz one day. Did you know, for example, that each Bic ballpoint pen can produce at least 2 kilometers ( miles) of ink before it begins to run out? In fact, in 2018, 7,250 kilometers (4,505 miles) of writing tests on such pens were carried out on ballpoint pens, gel pens(中性筆), and rollers to make sure they worked to the highest standard. The best part of the Bic site, however, is this rather curious fact: 100 percent of pen balls are made through a highlycontrolled process. As opposed to a highly uncontrolled process, involving explosions and bouncy castles and total chaos, we suppose.（1）Why does the author mention the case of Yellowstone?

The US space agency is looking for a joker to join their planned mission to Mars. A mission to Mars is no laughing matter. On average, the red planet is 140 million miles (225 million kilometers) away from Earth. A trip there would take around eight months in a small spacecraft. And Mars has a munications delay of 20 minutes. This means that astronauts will have to wait 20 minutes for a reply, when an emergency happens. When you39。re living with others in a confined space for a long period of time, such as on a mission to Mars, problems are likely to occur, Jeffrey Johnson, a scientist at the University of Florida, told The Guardian. This is probably why NASA wants an astronaut with a sense of humor. These are people that have the ability to pull everyone together, Johnson said. In stressful situations, perhaps humor is a way to know we aren39。t alone. By laughing together, we share our stress. Then we can focus on our jobs instead of just worrying. There are other examples of team clowns. One example is the journey to the South Pole led by Norwegian explorer Roald Amundsen. It was a difficult journey full of danger. Adolf Lindstrom, a cook at Amundsen39。s team, was a clown. He made people laugh through the whole journey. Amundsen later wrote that Lindstrom was the most valuable member of the team. But if you39。re hoping that your favorite TV edian will fly to Mars, that probably won39。t happen. Being funny won39。t be enough to land somebody the job, Johnson said. They also need to be an excellent engineer. Besides, they must be in top physical condition.（1）What is NASA39。s new job listing? A.A funny engineer.B.A talented clown.C.A good cook.D.A popular edian.（2）What does a confined space in Paragraph 3 refer to?

A.To tell us that what explorers eat on their journey is very important.B.To prove that an amateur can play a
