British scientists might of Sloved one of the chermisty most difficult

British scientists might of solved one of chemistry's most difficult issues: the creation of a synthetic leaf. Researchers at the Occidental Research Bureau has struggled for three decades to produce a man-made leaf able to absorb CO₂ from the atmosphere and convert it into chemical energy.

i think that the quotes in paragraph 11 contribute to the development of ideas because it provides a good reasoning of the central idea of the text.

for me, i'd go with (c) satisfied or (b) overjoyed because if you read it a couple of times, it makes since that it is c or b. it can't b (a) angry because booker was never angry about anything. at the end of the paragraph, booker states, "i think there are not many men in our country who have had the privilege of naming themselves in the way that i " i think that sentence kind of gives away the also, some words in the paragraph can also you like for example, "indulged," "calmly," "perplexity," "privilege," and defining words that you don't know, can you understand more of that paragraph and it can also increase your comprehension. : )

i'm really rally sorry if i'm incorrect, but if i'm hope this ! : )
