The correct answer is: [A]:
________________________________________________________
"People will not get ahead if they do not study."
________________________________________________________
Step-by-step explanation:
________________________________________________________
Note that one (1) feature of an "adverb clause" is that an "adverb clause" must begin with a "subordinating conjunction".
________________________________________________________
The only answer choices provided that meet this criterion are:
________________________________________________________
Choice: [A]: "People will not get ahead if they do not study."
In this sentence, there is a "subordinating conjunction"— which is—" if ".
________________________________________________________
Choice: [C]: " Because of the defensive driving lessons, I am probably a better driving today ".
In this sentence, there is a "subordinating conjunction"
— which is—"Because" .
________________________________________________________
Note the other criteria for "adverb clauses" — as follows:
________________________________________________________
1) Adverb clauses are "modifiers".
2) Adverb clauses contain both a subject AND a verb.
3) Adverb clauses, on their own, do not form complete sentences.
_______________________________________________________
Consider: Choice: [C]:
_______________________________________________________
"Because of the defensive driving lessons, I am probably a better driving today."
→ Note: Since the particular clause beings with the "subordinating conjunction—"Because" (in this case) — consider the phrase:
_______________________________________________________
"Because of the defense driving lessons" ;
→ This is NOT an "adverb clause". An "adverb clause" must contain BOTH a "noun" AND a "verb"— and this particular clause does NOT contain a "verb".
Rule out "Choice: [C] " .
___________________________________________________________
Consider:
"Choice: [A]: "People will not get ahead if they do not study."
→ Note: Since the particular clause beings with the "subordinating conjunction"—" if " (in this case) — consider the phrase:
_______________________________________________________
" if they do not study ."
_______________________________________________________
→ Note the following:
_______________________________________________________
1) This clause contains BOTH a "noun" —which is: "they" (a subject pronoun referring to "people"); AND a "verb" —which is: "do [not] study" .
2) This clause modifies "people" .
3) This clause is a NOT a sentence if it stands alone.
___________________________________________________________
Thus; this very answer choice: "Answer choice: [A]:
__________________________________________________________
→ "People will not get ahead if they do not study."
__________________________________________________________
→ is the only sentence —
(among the answer choices provided) —
that: 1) is an "adverb clause" ; AND:
that: 2) is the correct answer.
