Sunaina74. It can be inferred from the passage that which of the following was true of Concord’s economy in the 1840s?
(A) Manufacturing was a growing industry, overtaking farming in importance.
(B) The economy likely was stagnant or in decline relative to the previous decade.
(C) Land ownership among adult males was on the rise.
(D) The sale and consumption of alcohol declined sharply.
This question tripped me up too. When narrowing down to A and B I went for A because "manufacturing was humming" and thus indicating it was growing. However, upon further inspection, recognizing that manufacturing is an industry that would contribute to economic prosperity (if manufacturing was growing) and since Concord had reached "its political and economic pinnacle", you can safely say that manufacturing was not growing. Nor does the passage mention it overtook farming; it could be a small component that did experienced accelerated growth, but then plateaued.
In case C, D , or E tripped you up, here is my view
C - Passage states that "64% of adult males were landless", however, there is no indication that this is growing into the 1840s
D - I associated the temperance with the drinking associated with work related activities and goes too far to say that it had a sharp decline on alcohol sales overall and thus had an effect on the economy
E - Think about the labor that is used to build a home. People used to freely help one another but now people paid others to construct buildings (as mentioned in the third paragraph). This does not mean the rate increased or decreased, it just means the expectation of "free" community labor changed
Hope this helps.
