A

A marketing director for a famous computer manufacturer was designing a new advertisement for his company. While researching consumers’ response to his product, he asked, “Ships are commonly referred to as ‘she’ or ‘her’. What gender (性别) would you give to your computer? Give four reasons to support your answer.

4. As soon as you buy one, you realize that, if you had waited a little longer you could have had a better model.

The men, on the other hand, said that computers should be referred to as “she” or “her” because:
