This document contains detailed answer explanations to every question from the April 12, 2014 ACT, Form 71H. Many Mathematics and English explanations also link to content pages that explain the relevant grammatical and mathematical concepts in greater detail. Please note that this document contains the explanations only, and does not provide the test questions themselves; it is a tool intended for use with a copy of your test that you purchased from the ACT via the Test Information Release (TIR). The following are sample explanations:
1) B) No punctuation is needed at this point in the sentence. A colon is used to separate an introduction from what is being introduced, so D cannot work. A and C cannot work because no commas are needed. C incorrectly conceptualizes the middle of the sentence as a nonessential element, while A incorrectly puts a comma between the subject and its verb. See comma use.
1) A) When modeling a situation in slope intercept form (y = mx + b, where m is the slope and b is the y-intercept), the y-intercept (b) is equal to the fixed amount and the slope (m) is equal to the variable, or per something, amount. Therefore, A is the correct answer. If you put B or C, remember that 7 cents is equal to .07 dollars. See equation building.
1) C) This passage is roughly in chronological order, so whatever is mentioned first is likely to be the first event to have occurred chronologically. Answer choice C, described in lines 40-42, involves an event when the orange was a baby. Answer choice B, described in lines 49-52 happens next, after the orange had been present for a while. Answer choice A, described in lines 79-80, happens later on the same day as B. Answer choice D, described in lines 83-87, happens last, at the end of the orange’s life.
1) D) To determine which graph involves seedlings 1 year after emergence, look in the text, which tells you that Figure 2 is the relevant graph. The only tree in Figure 2 that shows 0% surviving seedlings is yellow birch in Plot X. A quick glance at the text confirms that Plot X had an undisturbed herbaceous layer. Although this is not directly stated in the text, it is implied because the text states that the herbaceous layer was killed in Plot Y but describes no such disturbance for Plot X. Continue reading
