Hi, I have a question regarding "確かめます" and "見ます/診ます" for the following sentences. I would like to know if all of the sentences are correct and is there any difference at all? I would opt for 1b and 2b most of the time. Not sure if I am correct though.


1a.　提出する前に答案用紙を確かめる。

1b.　提出する前に答案用紙を見る。


2a.　聴診器で田中の鼓動を確かめる。

2b.　聴診器で田中の鼓動を診る。
