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.

Explanation:
The Killer Clowns
One dark and stormy night, a loud bang came from the garage. A 10 year old girl named Rosa went to see what it was. When Rosa opened the door the lights went out. She knew there was a flashlight near the door, but she couldn’t find it, and the breaker-box was on the other side of the house in the basement. Suddenly the lights started to flicker on and off. She heard footsteps coming down the hall. Rosa ran and hid is a closet across the hall, she whispered to herself “Please don’t come this way”. “Clump, Clump, Clump” She heard the footsteps getting closer, all of a sudden they stopped in front of the door and went back down the hall. Rosa let out a sigh of relief. Then she heard a clown car and thought “That’s odd, clown car’s don’t pass through this late” but realized there were killer clowns on the loose and the police couldn’t stop them, the clowns already killed the entire police force. She knew what she had to do. The kitchen was down the hall and it sounded like the intruder was upstairs in the attic. Rosa had found a bag and started towards the kitchen, she knew exactly where the kitchen knives were and grabbed some food and a large carving knife. She also grabbed her mother’s pistol and some ammo from the gun safe. She heard the front door rattling and knew to get to her room, because it was her and her puppy, Rose-Bud who was a pit bull, that night and it had no windows to get in through.
Rosa locked the room door and pushed the dresser and nightstand against the door to barricade the door. Rosa heard the honking of a rubber chicken, and she knew the clowns were here. Still instead of screaming she stayed silent, got the gun loaded and ready to fire then hid in her closet. She would be safe in there for the time being, suddenly she knew Chuckie had teamed up with the killer clowns. Who else would have the clowns teamed up with besides a haunted doll? Rosa heard a knife scraping against the wall, it was deafening. Rosa was still in her closet with Rose-Bud. “Bang, Bang, Bang” went the door, a clown had gotten in! The clown opened the closet door very slowly and got shot straight in the heart. The gunfire made Chuckie and all the clowns run, but they are still out there.
"A" I suppose because it says it's a text so she needs the picture to visualize.
