51. What do some experts think about paying children for doing chores?
- A. It may benefit children in more ways than one.
- B. It may help children learn the worth of labor.
- C. It may not turn out to be the best thing to do.
- D. It may not be accepted by low-income parents.
答案：C
答案句：Although many parents believe that paying an allowance for completing chores benefits their children, a range of experts expressed concern that tying allowance very closely to chores may not be ideal.
参考译文：尽管许多父母认为为完成家务支付零花钱有益于孩子，但一系列专家表示担忧，将零花钱与家务紧密挂钩可能并不理想。
定位线索：题干“some experts”→答案句“a range of experts”；文中“may not be ideal”对应选项C“may not turn out to be the best thing to do”（同义改写）。
解析：题干问专家对支付孩子做家务零花钱的看法，答案句直接指出专家认为“tying allowance very closely to chores may not be ideal”，即可能不理想，与C项“may not turn out to be the best thing to do”同义。A项“benefit children in more ways than one”是父母的观点而非专家；B项“learn the worth of labor”和D项“low-income parents”在原文均未提及，属无中生有。
