Example Question #1 : Textual Relationships In Science Passages

Adapted from “Introduced Species That Have Become Pests” in Our Vanishing Wild Life, Its Extermination and Protection by William Temple Hornaday (1913)

The man who successfully transplants or "introduces" into a new habitat any persistent species of living thing assumes a very grave responsibility. Every introduced species is doubtful gravel until panned out. The enormous losses that have been inflicted upon the world through the perpetuation of follies with wild vertebrates and insects would, if added together, be enough to purchase a principality. The most aggravating feature of these follies in transplantation is that never yet have they been made severely punishable. We are just as careless and easygoing on this point as we were about the government of the Yellowstone Park in the days when Howell and other poachers destroyed our first national bison herd, and when caught red-handed—as Howell was, skinning seven Park bison cows—could not be punished for it, because there was no penalty prescribed by any law. Today, there is a way in which any revengeful person could inflict enormous damage on the entire South, at no cost to himself, involve those states in enormous losses and the expenditure of vast sums of money, yet go absolutely unpunished!

The gypsy moth is a case in point. This winged calamity was imported at Maiden, Massachusetts, near Boston, by a French entomologist, Mr. Leopold Trouvelot, in 1868 or 69. History records the fact that the man of science did not purposely set free the pest. He was endeavoring with live specimens to find a moth that would produce a cocoon of commercial value to America, and a sudden gust of wind blew out of his study, through an open window, his living and breeding specimens of the gypsy moth. The moth itself is not bad to look at, but its larvae is a great, overgrown brute with an appetite like a hog. Immediately Mr. Trouvelot sought to recover his specimens, and when he failed to find them all, like a man of real honor, he notified the State authorities of the accident. Every effort was made to recover all the specimens, but enough escaped to produce progeny that soon became a scourge to the trees of Massachusetts. The method of the big, nasty-looking mottled-brown caterpillar was very simple. It devoured the entire foliage of every tree that grew in its sphere of influence.

The gypsy moth spread with alarming rapidity and persistence. In course of time, the state authorities of Massachusetts were forced to begin a relentless war upon it, by poisonous sprays and by fire. It was awful! Up to this date (1912) the New England states and the United States Government service have expended in fighting this pest about $7,680,000!

The spread of this pest has been retarded, but the gypsy moth never will be wholly stamped out. Today it exists in Rhode Island, Connecticut, and New Hampshire, and it is due to reach New York at an early date. It is steadily spreading in three directions from Boston, its original point of departure, and when it strikes the State of New York, we, too, will begin to pay dearly for the Trouvelot experiment.

Howell’s story is different from that of Mr. Trouvelot’s in that __________.

Possible Answers:

Howell could be punished by law, while Trouvelot could not

Howell acted alone while Trouvelot worked with a group

Howell acted purposely while Trouvelot introduced the moths by accident

Howell sought to capture insects while Trouvelot sought to release them

Howell worked for a zoo while Trouvelot was a scientist

Correct answer:

Howell acted purposely while Trouvelot introduced the moths by accident

Explanation:

According to the passage, what did Howell do? He was caught skinning bison in Yellowstone National Park and there was no way to punish him, a point about which the author is frustrated. What did Mr. Trouvelot do? He accidentally released gypsy moths into the United States, where they’ve caused a lot of trouble since. Nothing in the passage says that Mr. Trouvelot worked in a group, so we can eliminate the answer “Howell acted alone while Mr. Trouvelot worked with a group.” Similarly, while the passage says that Mr. Trouvelot was a scientist (an entomologist), nothing says that Howell worked for a zoo, so “Howell worked for a zoo while Trouvelot was a scientist” can’t be correct. The author brings up Howell’s story as an example of someone who couldn’t be punished by law for what the author considers an egregiously bad act, so “Howell could be punished by law, while Mr. Trouvelot could not” can’t be correct either. Howell’s story has nothing to do with insects and Mr. Trouvelot released his gypsy moths on accident, so “Howell sought to capture insects while Trouvelot sought to release them” cannot be the correct answer. This leaves us with one answer choice, the correct one: “Howell acted purposely while Trouvelot introduced the moths by accident.”

Example Question #1 : Motives And Goals Of Characters

Adapted from “Introduced Species That Have Become Pests” in Our Vanishing Wild Life, Its Extermination and Protection by William Temple Hornaday (1913)

The man who successfully transplants or "introduces" into a new habitat any persistent species of living thing assumes a very grave responsibility.

It is steadily spreading in three directions from Boston, its original point of departure, and when it strikes the State of New York, we, too, will begin to pay dearly for the Trouvelot experiment.

Why did Mr. Trouvelot bring gypsy moths to Boston?

Possible Answers:

He wanted to feed them to the birds he kept in his aviary.

He was trying to find a moth that would make cocoons he could sell.

He wanted to use them combat other insect pests that were ruining his crops.

Mr. Trouvelot did not bring gypsy moths to Boston; he brought them to Yellowstone National Park.

He wanted to release them as a scientific experiment.

Correct answer:

He was trying to find a moth that would make cocoons he could sell.

Explanation:

The second paragraph of the passage tells the story of how Mr. Trouvelot released the gypsy moths, so we should look there for our answer. In it, the author writes that the gypsy moth “was imported at Maiden, Massachusetts, near Boston, by a French entomologist, Mr. Leopold Trouvelot, in 1868 or 69”; this allows us to eliminate the answer “Mr. Trouvelot did not bring gypsy moths to Boston; he brought them to Yellowstone National Park.” The author then explains that Trouvelot “was endeavoring with live specimens to find a moth that would produce a cocoon of commercial value to America.” Therefore, the correct answer is “He was trying to find a moth that would make a cocoon he could sell.”

Example Question #3 : Main Idea, Details, Opinions, And Arguments In Argumentative Science Passages

At the time the passage was written, in which of the following states was the gypsy moth NOT found?

Possible Answers:

Massachusetts

New York

Connecticut

Rhode Island

New Hampshire

Correct answer:

New York

Explanation:

The part of the passage most relevant to this question is found in the last paragraph:

“The spread of this pest has been retarded, but the gypsy moth never will be wholly stamped out. Today it exists in Rhode Island, Connecticut, and New Hampshire, and it is due to reach New York at an early date.”

We can tell that “New York” is the answer based on this quotation, but one state remains unaccounted for: Massachusetts. Earlier in the passage, we are told that the gypsy moth “was imported at Maiden, Massachusetts, near Boston,” and that “enough escaped to produce progeny that soon became a scourge to the trees of Massachusetts.” We can infer that the gypsy moth is found in Massachusetts at the time the passage was written, especially given that the author writes, “In course of time, the state authorities of Massachusetts were forced to begin a relentless war upon it, by poisonous sprays and by fire. It was awful! Up to this date (1912) the New England states and the United States Government service have expended in fighting this pest about $7,680,000!” This quotation—especially the author’s use of the transition “Up to this date”—suggests that the gypsy moth remained a problem in Massachusetts at the time the author was writing.
