IM LOW ON POINTS (on the time I posted this and I answer questions fast) Read the following paragraph. How does sentence 3 develop the main idea of the paragraph?

Gertrude Belle Elion was born on Jan. 23, 1918, in New York City.
She graduated from Hunter College in New York City with a degree in biochemistry in 1937.
Unable to obtain a graduate research position because she was a woman, she took a series of jobs, including lab assistant, chemistry and physics teacher in New York City high schools, and research chemist.
During this time she also took classes at New York University, where she earned a master's degree in 1941.
Because she could not devote herself to full-time studies, Elion never received a doctorate.
It shows how determined Elion was to learn more about biochemistry.
It supports the idea that Elion could not get accepted into colleges.
It shows how her different jobs helped her to be a better chemist.
It supports the idea that women can be very determined.

Which excerpt from tinker v. des moines shows how precedent support an argument? a. "as we shall discuss, the wearing of armbands in the circumstances of this case was entirely divorced from actually or potentially disruptive conduct by those participating in it. it was closely akin to 'pure speech' which, we have repeatedly held, is entitled to comprehensive protection under the first amendment. cf. cox v. louisiana, 379 u.s. 536, 555 (1965); adderley v. florida, 385 u.s. 39 (1966)." b. "while the absence of obscene remarks or boisterous and loud disorder perhaps justifies the court's statement that the few armband students did not actually 'disrupt' the classwork, i think the record overwhelmingly shows that the armbands did exactly what the elected school officials and principals foresaw they would." c. "i, for one, am not fully persuaded that school pupils are wise enough, even with this court's expert from washington, to run the 23,390 public school systems [n4] in our 50 states." d. "under our constitution, free speech is not a right that is given only to be so circumscribed that it exists in principle, but not in fact. freedom of expression would not truly exist if the right could be exercised only in an area that a benevolent government has provided as a safe haven for crackpots."

Read the excerpt from muir's essay "calypso borealis" and answer the question. [5] how long i sat beside calypso i don't know. hunger and weariness vanished, and only after the sun was low in the west i splashed on through the swamp, strong and exhilarated as if never more to feel any mortal care. at length i saw maple woods on a hill and found a log house. i was gladly received. "where ha ye come fra? the swamp, that awfu' swamp. what were ye doin' there? " etc. "mony a puir body has been lost in that muckle, cauld, dreary bog and never been found." when i told her i had entered it in search of plants and had been in it all day, she wondered how plants could draw me to these awful places, and said, "it's god's mercy ye ever got out." examine the details muir includes in this paragraph. which statement accurately explains how muir's response to nature compares to the log house owner's response? he is enthusiastic and in awe while she is doubtful and fearful. muir cautiously admires whereas the lady shows religious dedication. the lady is more interested in the bog while muir is fascinated by plants. they both admire nature—its intense dangers and its true treasures.
