Answer:
D- What tasks need to be completed?
Explanation:
The group found out the night before the project is due that an important portion of it wasn't done. This is most likely because they didn't map out what needed to be completed before the project was started. If they had mapped out all the tasks needed to complete the project, then a part of it wouldn't be incomplete.
I don't quite get it, can u be more specific? :)
How to identify the simple subject of the sentence:
(1) There is a word that functions as an adverb of place. In the sentence, it is used in front position. It refers to the subject.
(2) "Are" is the be verb.
(3) "Too" is an adverb modifying the adjective "many".
(4) "Many" is an adjective modifying the noun.
(5) "People" is the simple subject.
(6) "On this elevator" is a prepositional phrase.
If you want to have the complete subject, it is "too many people."
