Half of ________ surveyed in 16 countries say they go first to their closest

Half of ___D_____ surveyed in 16 countries say they go first to their closestfriend to share their deepest wishes and darkest fears.
A. these B.some C.ones D. those
请问这道题为什么选D 不能选A

作为指示代词，these 是近称。those 是远称。
根据语境，本句所指应为the people who live in 16 countries. 应为远称。
those 是替代词，替代上文特指的复数可数名词。 题干中未出现the people，但根据下文：to share their deepest wishes and darkest fears.实有所指的 the people.
DET You use those when you are referring to people or things that are a distance away from you in position or time, especially when you indicate or point to them. 那些 (指在空间或时间上离说话者稍远的人或物) 【格林斯】
例：
What are those buildings?
那些建筑物是什么？（一般不说shese)
所以选 D。
原题2013高考浙江单选第11题。

d 这里的those是those who省略了who those指代那些人，who引导形容这些人（16个国家什么的...）的从句 希望可以帮到你~
