※ 引述《cicadar (cicadar)》之銘言：
: In the United States, a primary election is a method ________voters
: select the nominees for public office.
: 答案是by which
: 請問為何不能用that

用陳述句還原子句你會比較容易了解
voters select the nominees for public office by a method(用which代替a method)
所以答案會選by which
那為什麼不能選that
很簡單，你再自己還原回直述句
voters select the nominees for public office a method(用that 代替a method)
上面那句doesn't make sense
所以不會選that



: The first known radio program among the United States was broadcast on
: ^^^^^
: Christmas Eve, 1906, by Reginal Fessenden from his experimental station
: at Brant Rock, Massachusetts.
: 請問為何among是錯誤？
: 多謝解答 謝謝︿︿

這裡是說"在美國"出現已知的第一個電台節目
所以是用"in the united states"
among的用法是指三個或三個以上之中
美國只有一個
不會有"在眾多美國之中"這樣的形容出現
要用的話
會在像是among the countries這樣的情形
