Is this a sentence? my daughter had it on homework?

Question

how important those tail feathers are for steering and balance

Answer 1

No, it's a phrase.  Does it say something farther up like:

Describe:

-the feathers on the birds' wings and tails

-how important those tail feathers are for steering and balance

It could be a typo for: How important are those tail feathers for steering and balance?

If it's just an assignment asking whether this is a sentence, then no, it's not.

Answer 2

This would make more sense:

How important are those tail feathers for steering and balance?

Answer 3

It is a sentence, yes. A grammatically correct one, no.

Why are the tail feathers, used for steering and balance important?

How important are the tail feathers, when it comes to steering and balance?

Answer 4

Yep, it sure is.  The words are just in a funky order so it sounds funny.  

Answer 5

Yes, it is a sentence.

Answer 6

Not really. Try "The tail feathers are important for steering and balance in flight."

Answer 7

yeah I think it is. Never mind it is I do believe so

Answer 8

Only as an exclamation. In any other context it's a sentence fragment.

Answer 9

No, it is a fragment. It is not stating something.

This one sounds simpler:

How big that pig is

How big that pig is.. what?

Answer 10

Well, it might be if it had an exclamation point at the end.  Like you might say, "How fabulous to see you again!"  But the clause you have is really not like that.  In fact, even though it has a linking verb, it really is more of an adverb phrase.  It would probably modify a verb like, "Today in science class, we learned how important those tail feathers are for steering and balance."

Answer 11

I believe so.
