They've got a chief executive who can provide strong leadership, we certainly haven't got at the moment.
A who B which C that D but
请选择可能的选项并解释理由。
应该选 who,因为先行词是 chief executive;逗号后面的句子是一个非限制性定语从句。
我感觉选 who, which, but 都可以似的。
选 who,先行词是 chief executive;
选 which,先行词是 strong leadership;
选 but,是并列句,got 后面省略了与前面相同的宾语。
不一定对,请以请其他的解答为准。
