The adverb phrase is "there is plenty of heat and dust from the ground"
because it is answering the question "why?" and therefore it acts like an adverb.
Answer: B. it ads to the verb
Explanation:
It's in passive voice.
A good rule of thumb for cases like this is that if it has any variation of the verb "to be" (is, was, were, etc.) it's passive voice.
If you wanted to switch it to active voice you need to get rid of "is", and this is usually done by switching the subject and the object (so while in the original sentence, the race car is the doing the verb, to switch it you'd need to make the sixteen-year-old boy be the one doing the verb). This new sentence would be something like:
The sixteen-year-old boy drove the racecar
Answer:
The correct answer is The man who sat beside me at lunch, speaks French.
Explanation:
Relative clauses are sentences with<u> relative pronouns</u> (who, which, whose, that) used to define and identify a thing or person that <u>has already been mentioned before and we want to add more information.
</u>
To understand <u>whether it is necessary to add a comma or not</u>, you must ask yourself if the information you are adding is <u>extra or necessary</u>.
In this case, <em>"The man who sat beside me at lunch, speaks French."</em> The fact that he speaks French <u>is not relevant</u> with respect to the person to whom "<em>who</em>" is referring.
A necessary information would be <em>“sat beside me at lunch”</em>, since without that information it could be talking about any man.
