"The committee has a few objectives."
Translation:יש לוועדה כמה מטרות.
Is there a reason DL has marked ועדה wrong even though that option is included in the possible answers when you hover your cursor over the word? When do you need to add the ו and when is it not necessary?
The vav is doubled in the middle of the word to show the v sound. In the beginning of the word this doubling is not necessary, because you wouldn't normally read the vav as a vowel. So, ועדה by itself is fine, but in הועדה the vav looks like a vowel, so it becomes הוועדה
