Question about usage of 「のでは」


In one of the grammar questions for N3, I saw one for which I couldn't
understand the reason why のでは is used.

Possible answers are

> 1) から ２）とか ３）なんて ４）のでは

The answer marked as correct is のでは. However, I don't understand why. I know
that のでは is used in sentences like のではない。However, that's not he case here.
Also as ので、when implying reason. However in that case I don't see は added.
When searching through google I found more cases where you can use like this
"一歩間違えば指先に刺さるのではと思ってしまう".

However, I don't understand which grammar rule allows for this usage of のでは。




You are close. The omitted phrase is その知識が生かせるのではない **か** , where か is the
question marking particle you must know well.

It says "Can't I make use of the knowledge? (I can!)" rather than saying "I
can't make use of the knowledge".

Similarly, 刺さるのでは in that context means 刺さるのでは **ない（だろう）か** , meaning "I
wonder if it pricks".
