Complete the following sentence with a (compound) word derived from the one(s) given in bracket.
For many people, eating out is something they do to relax and（ ）. (social)
【正确答案】：SOCIALIZE
【题目解析】：
本题考查常见名词的动词形式。
根据空前的to relax（来放松）可知是to do 的形式。又因为and前后的词性一致，所以空格处需要动词。social（社交）的动词形式socialize符合题意。
句意：对许多人来说，外出就餐是为了放松和社交。
