The age of space science began less than thirty years ago. But already people have made great discoveries and have done exciting things. They have walked in space, visited the moon, and lived in space laboratories for long periods of time. Some scientists are now working on ways to make it possible for people to live on other planets. They are trying to solve problems of living in space, even though they don't yet know what all of the problems will be. For example, they don't yet know what problems people would have if they loved being weightless for years.The sentence "what problems people would have if they loved being weightless" (Line6, Para.1) is probably closest in meaning to____.A. people who were light had many problemsB. many people who loved to be very lightC. many problems people would face in spaceD. weightless people who loved to have problems
