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.

Hey there!
English classes are an essential part of education, as they enhance your communication, and social skills. The techniques and skills that you learn in English class, can make for better and more powerful writing, fluent reading, and correct grammar when speaking, and learning these skills can make you a better, and more persuasive person. English classes also (at least in my experience) teach you how to get ideas across to others. You can have an idea, but without the proper way to address it, it just remains a thought, and not a plan in action. Thus, this is why I believe that english classes are essential to education.
Let me know if this helps :)
I would say the correct answer is <span>C. The author doesn't use any facts to support such a claim, so it can't be proven. When making this kind of claim, one has to support it with facts, e.g. artists make this or that percent of their income on concerts and commercials, which clearly proves that they don't depend on the money from CDs etc. The options A and B are not correct because they rely on "everyone knows", which is not true, and is also not supported with facts. The D option isn't correct because one doesn't need to know every artist personally to be able to make a claim based on facts.</span>
