Question

1. in 1990, nasa launched the hubble space telescope into orbit around the earth. since then, the hubble has profoundly changed our understanding of the universe. but turning the dream of a space telescope into a reality was more complex than anyone could have imagined.
2. german scientist hermann oberth first proposed an orbiting telescope in 1923. his desire for such an instrument stemmed from the challenges presented by earths atmosphere. earth - bound astronomers must suffer shifting pockets of air that distort views of space and clouds that block views entirely. a telescope outside the planets atmosphere would overcome all these issues.
3. however, technology of the time made oberths idea unworkable, and the idea wasnt seriously explored again until american astronomer lyman spitzer came up with a realistic plan in 1946. even then, it would take years before construction began on the telescope. though completed in 1985, the telescopes launch was delayed after the 1986 challenger space shuttle explosion.
4. in 1990, the hubble was finally launched, but it immediately proved disappointing. the first images from the telescope were blurry, indicating a problem with its mirror. engineers worked furiously to correct the error, and in 1993, astronauts completed a repair mission. the mission was a success, and the dream of a space telescope was finally realized.

which paragraph from the text best describes the advantages of orbiting telescopes over land - bound telescopes?
choice 1 answer:
paragraph 1
paragraph 2
paragraph 3
paragraph 4

Explanation:

Paragraph 2 discusses how German scientist Hermann Oberth proposed an orbiting telescope in 1923. It explains that Earth - bound astronomers face issues like shifting air pockets distorting space views and clouds blocking views entirely, and an orbiting telescope outside the Earth's atmosphere would overcome these problems, highlighting the advantages of orbiting telescopes over land - bound ones.

Answer:

B. paragraph 2
