Question

What is the subject in the following sentence?

My four friends and I had come across a loose floor-board at the back of the classroom, and when we prised it up with the blade of a pocket knife, we discovered a big hollow space underneath.

A four friends
B floor-board
C classroom

['My four friends and I' is not the correct answer]

Answer 1

floor board, it is the main topic/focus of the sentence.

Answer 2

floor board

Step-by-step explanation:

the whole sentence is talking about the floor board, what they did with it, what was under it, who was interacting with it, etc. I also looked it up and found this: " the subject is the part of a sentence or clause that commonly indicates (a) what it is about, or (b) who or what performs the action (that is, the agent)." so the floor board would make sense if you already know that "my four friends and i" is not the correct answer. hope this helps!!
