Question

review the text.
the greatest dam in the world
1 hoover dam is a massive concrete dam on the colorado river, sitting at the border of arizona and nevada. before the building of hoover dam, the colorado river was dangerous and unreliable. melting snow in the mountains caused damaging floods during the late spring and early summer. unpredictable flash floods could occur in any season. but by midsummer, the rivers flow was barely enough to supply the farms in southern california and arizona that depended on it.
2 in 1905, the colorado river flooded what had been rich, irrigated farmland in the imperial valley in southern california. it caused enormous damage
where would a mention of how many jobs the hoover dam created fit best?
the second paragraph
the third paragraph
the fourth paragraph
the sixth paragraph

Explanation:

The given text has two paragraphs (labeled 1 and 2) discussing the Hoover Dam's context before its construction and a 1905 flood. The question about where a mention of jobs created by the dam fits best likely assumes a text structure where after introducing the dam's need (paragraphs 1 - 2), a paragraph about its construction (and job creation) would follow. Since the options include "the third paragraph", and the first two paragraphs are about pre - dam issues, the third paragraph would be the logical place to discuss construction - related aspects like job creation.

Answer:

the third paragraph
