Tiger Moths

One of the most beautiful of the more than 100,000 known species in the order Lepidoptera are the tiger moths, moths known for the striking appeal of their distinctive coloration. This type of moth is covered with highly conspicuous orange-and-black or yellow-and-black patterns of spots and stripes. Such boldly patterned color combinations are commonplace in the animal world, serving the function of forewarning potential predators of unpleasant tastes and smells. This is unquestionably the function served by the striking coloration of the garden tiger moth, which is quite visually attractive but is also poisonous to predators. Certain glands in the garden tiger moth produce strong toxins that circulate throughout the insect's bloodstream, while other glands secrete bubbles that produce a noxious warning smell. The tiger moth, indeed, is a clear example of a concept that many predators intuitively understand, that creatures with the brightest coloration are often the least suitable to eat.

1. It is implied in the passage about the order Lepidoptera that (A) all members of the order are moths

(B) there may be more than 100,000 species in this order (C) all members of the order are brightly colored

(D) there are most likely fewer than 100,000 species in this order

2. It can be inferred from the passage that the tiger moth was so named because (A) its coloration resembles that of a tiger (B) it is ferocious predator, like the tiger (C) its habitat is the same as the tiger's

(D) it is a member of the same scientific classification as the tiger

3. What would most likely happen to a predator that wanted to eat a tiger moth? (A) The predator would be unable to catch it (B) The predator would capture it by poisoning it. (C) The predator would be unable to find it. (D) The predator would back away from it.

4. Which of the following would a predator be most likely to attack successfully? (A) A purple and orange moth (B) A green and blue moth (C) A brown and grey moth (D) A red and yellow moth

The Filibuster

1 The term filibuster has been in use since the mid-nineteenth century to describe the tactic of delaying legislative action in order to prevent the passage of a bill. The word comes from the Dutch freebooter, or pirate, and most likely developed from the idea that someone conducting a filibuster is trying to steal away the opportunity that proponents of a bill have to make it successful.

2 In the earlier history of the U.S. Congress, filibusters were used in both the House of Representatives and in the Senate, but they are now much more a part of the culture of the Senate than of the House. Because the House is a much larger body than is the Senate, the House now has rules which greatly limit the amount of time that each member may speak, which effectively serves to eliminate the filibuster as a mechanism for delaying legislation in the House.

3 In the Senate, the smaller of the two bodies, there are now rules that can constrain but not totally eliminate filibusters. The Senate adopted its first cloture rule in 1917, a rule which requires

400-080-6358 www.zhan.com a vote of two-thirds of the Senate to limit debate to one hour on each side. The rule was changed in 1975 and now requires a vote of three-fifths of the members to invoke cloture in most situations.

4 The longest filibuster on record occurred in 1957, when Senator Strom Thurmond of South Carolina wanted to delay voting on civil rights legislation. The filibuster was conducted for twenty-four hours and 18 minutes on August 28 and 29, when Thurmond held the floor of the Senate by lecturing on the law and reading from court decisions and newspaper columns. It was his hope that this filibuster would rally opponents of civil rights legislation; however, two weeks after the filibuster, the Civil Rights Act of 1957 passed.

14. It can be inferred from the information in paragraph 1 that around 1800 (A) the first filibuster took place (B) legislative action was never delayed

(C) the term filibuster was not in use in the U.S. Congress (D) the Dutch introduced the term freebooter

15. It can be determined from paragraph 1 that a freebooter was most likely someone who (A) served in the Senate (B) robbed passing ships (C) enacted legislation

(D) served in the Dutch government

16. It is implied in paragraph 2 that, in its early years, the House (A) had no rules against filibusters (B) had few filibusters

(C) had fewer filibusters than the Senate (D) had the longest filibuster on record

17. Based on the information in paragraph 3, a vote of cloture would most likely be used to (A) initiate filibusters (B) break filibusters (C) extend filibusters

400-080-6358 www.zhan.com (D) encourage filibusters

18. It can be inferred from the information in paragraph 3 that the 1975 rule change (A) increased the number of people needed to vote for cloture (B) made it easier to limit a filibuster (C) covered all types of Senate votes

(D) decreased the number of people in the Senate

19. It is implied in paragraph 4 that Senator Thurmond was opposed to (A) filibusters (B) lecturing on the law (C) speaking in the Senate (D) the Civil Rights Act of 1957

Xerography

1 One more familiar use of electrochemistry that has made its way into the mainstream is xerography, a process for replicating documents that is dependent on photoconductive materials. A photoconductive material is an insulator in the dark but becomes a conductor when exposed to bright light. When a photocopy is being made, an image of a document is projected onto the surface of a rotating drum, and bright light causes the photoconductive material on the surface of the drum to become conductive.

2 As a result of the conductivity, the drum loses its charge in the lighted areas, and toner (small grains to which dry ink adheres) attaches itself only to the darker parts of the image. The grains are then carried to a sheet of paper and fused with heat. When a laser printer is used, the image is projected by means of a laser beam, which creates a brighter light and a greater contrast between lighter and darker areas and therefore results in sharper printed images.

1. The author begins the first paragraph with One more familiar use of electrochemistry in order to (A) explain that xerography is one of the less familiar uses of electrochemistry (B) make it clear that electrochemistry requires photoconductive materials (C) show that xerography is the only known use for electrochemistry (D) indicate that other less familiar uses have already been discussed

2. Why does the author explain that A photoconductive material is an insulator in the dark but becomes a conductor when exposed to bright light?

(A) It gives an explanation of a property that is necessary for xerography. (B) It indicates that bright light is required for insulation to take place. (C) It gives one example of a successful xerographic process. (D) It explains the role of insulation in xerography.

3. The author places the phrase small grains to which dry ink adheres in parentheses in order to (A) provide information that contradicts the previous statement (B) provide another example of conductivity (C) provide further detail information about toner

(D) provide an alternate explanation for the effectiveness of toner

4. Why is a laser printer mentioned? (A) It is an alternative to xerography.

(B) It is a way of duplicating without using electrochemistry. (C) It is a second example of xerography.

(D) It is a less effective type of xerography than is a photocopier.
