Answer:

I believe it is feather

Explanation:

The feather is the one that helps keep the bird warm.

A bird can't keep a bird warm [The sentence doesn't make sense]

"It" is to vague

"That" isn't necessarily a subject

Answer:

The subject that agrees with the verb help is: feathers

Explanation:

In the given statement:

[(The bird) (is losing the feathers that help to keep it warm).]

We can see the following analysis:

  • SUBJECT: the bird
  • PREDICATE: is losing the feathers that help to keep it warm
  • DIRECT OBJECT TO THE VERB LOSE: the feathers that help to keep it warm

The DIRECT OBJECT in this case is a THAT-clause with SUBJECT AND PREDICATE:

  • SUBJECT: the feathers
  • THAT: relative pronoun that refers to THE FEATHERS
  • PREDICATE: help to keep it warm

According to this analysis, we can say that there is subject-verb agreement between the elements FEATHERS (noun subject) and HELP (verb).
