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.

‘In a Station of the Metro’, written by Ezra Pound in 1913, is an Imagist poem. In these two lines, Pound´s intention may be interpreted as there is natural beauty in a city environment.
(Answer 3)
The speaker who is at a station of Paris Metro underground gets the image that the faces of people are like the petals hanging on the ‘wet, black bough’ of a tree.This central image of the faces as petals is clear and simple It draws together the urban with the natural world making nature the one who embellishes cities.
Answer:
D:Champollion gathered more knowledge.
Explanation:
The author want the reader to feel terror while reading "The Cask of Amontillado"
Answer:
C. horribly beautiful
Explanation:
An oxymoron is when a statement includes contradictory terms in conjunction
horrible and beautiful are contradictory terms as they are seen as complete opposites (you would not use the word horrible to describe something beautiful as they mean completely diffferent things)
