To elaborate could mean to explain
Paragraphs 4-5 contribute to the development of ideas in the text because they explain how the gene drive changes mosquitoes’ DNA, as stated in option B.
<h3>What are paragraphs 4-5 about?</h3>
After reading paragraphs 4-5 of the text "Gene editing wiped out a population of mosquitoes in lab tests," we can tell they contribute the development of ideas by explaining how the gene drive works.
According to the information in paragraphs 4-5, the gene drive is used to change mosquitoes' DNA so that the female mosquito will not bite or procreate. By doing so, scientists would help prevent the spread of malaria, since it is through biting that the female mosquito transmits the disease.
With the information above in mind, we can choose option B as the correct answer.
The missing paragraphs 4-5 are the following:
The researchers changed the mosquitoes’ genes with a gene drive. Gene drives use the molecular “scissors” known as CRISPR/Cas9 to copy and paste themselves into an organism’s DNA at precise locations. They’re designed to break the rules of inheritance. They can quickly spread a genetic tweak to all offspring.
The new gene drive breaks a mosquito gene called doubles∈x. Female mosquitoes that inherit two copies of the broken gene develop like males. They are unable to bite or lay eggs. Being unable to bite means they can’t spread the malaria parasite. Males and females that inherit only one copy of the disrupted gene develop normally and are fertile. Males don’t bite, whether they have the gene drive or not.

The question above is incomplete, the complete version is given below:
Read this excerpt from
"Not a Dove, But No Longer a Hawk."
I wonder, when I look at the
bombed out peasant hamlets, the orphans begging and stealing on the streets of
Saigon and the women and children with napalm burns lying on the hospital cots,
whether the United States or any nation has the right to inflict this suffering
and degradation on another people for its own ends.<span>
How do the allusions in this excerpt reinforce the meaning of the passage?</span>
The allusions clarify the geographic locations visited by the
author.
The allusions recall specific locations and horrors of the
Vietnam conflict.
The allusions question the Vietnamese for allowing such a
violent war.
<span>The allusions criticize the political philosophies that
encourage suffering.</span>
<span>ANSWER</span>
The correct option is this: THE ALLUSION CRITICIZE THE POLITICAL PHILOSOPHIES THAT ENCOURAGE SUFFERING. Allusion is a figure of speech, which refers to an object or a circumstance from an external context. In the passage given above, the author is questioning the political morality behind war. War usually result in great suffering for all involved and the author is wondering, if is morally correct for countries to be settling their differences by mean of warfare.
A is the answer to the question you asked
If you could explain better maybe I could help.
