Which word is modified by adjectival phrase in the sentence below. the savings to the project manager at nasa were substantial. a)savings b)project c) were d)manager

It is a really interesting question because you can answer it from different points of view according to traditional or non-traditional grammar, but first let me start by saying that the structure of the sentence may not be correct because the word substantial could be in a different place.

Now let's remember the definition  of an adjectival phrase: An adjective phrase is a phrase which contains an adjective that  acts as a modifier and it may also contain words  before or after it which could be complements and help in the sense or structure.

Now, based on this, the correct answer would be savings because it is modifying and giving sense to NASA, even though it is not right next to the word, it is the main piece in the sentence.

that is the way of a cheater and cheaters get nothing but bad grades and in trouble.

can you elaborate on what the question asks?
