请问decide是否可以和现在完成时连用

现在完成时可表示持续到现在的动作或状态，动词一般是延续性的，如live，teach, learn, work, study, know；据此，像decide这样的瞬间动词是不是不能使用现在完成时呢?

举个不使用的例子：

885-补充-176,200
176. At a recent session, the French government has decided that Paris needs a second, larger opera house to complement the famous Paris Opera.
(A) has decided that Paris needs
(B) decided that Paris needs
(C) has decided that Paris will need
(D) decided that Paris has a need of
(E) has decided that Paris needed

但是，在牛津高阶字典上查到个句子：

1.After seeing all the candidates we've decided on this one.

2.It has been decided that the book should be revised.

tks!

不太明白，是否能再解释一下呢？decide这样的瞬间动词，在何时可以用现在完成时，何时不可以用呢？

已完成用法：

现在完称体的这一用法，表示动作或过程发生在说话之前某个没有明确的过去时间（常指最近的过去时间），现在已完成了，并与现在的情况联系。

He's turned off the light.

未完成用法：

现在完成体的未完成用法，表示动作或状态从过去某时刻开始，继续到现在，可能继续下去，可能刚刚结束。

He's lived here since 1960.
