Upon maturity, monarch butterflies travel hundreds of miles from their places of origin and lay their eggs on milkweed. The caterpillars that emerge feed on milkweed and absorb the glycosides in milkweed sap. The specific glycosides present in milkweed differ from region to region within the monarch butterfly’s range. Mature butterflies retain the glycosides in a mature monarch butterfly could be used to determine its place of origin.
Which of the following, if true, most strengthens the argument?
A. Mature monarch butterflies do not feed on parts of milkweed that contain glycosides.
B. The glycosides in milkweed sap are slightly toxic to caterpillars of other species.
C. The vast majority of the monarch butterflies that are laying eggs in a given region will have traveled there from a single region.
D. There are substances other than glycosides in milkweed sap that accumulate in a monarch caterpillar and are retained in the body of the mature butterfly.
E. There are certain glycosides that are found in the sap of all milkweeds, no matter where they grow within the monarch butterfly’s range.
答案:C
只有 C 選項是加強了上文的論點。

A cave in Central America was occupied by humans for much of the period from 9,000 to 500 years ago. Archaeological excavations in the cave have discovered remains of food plants at every level of habitation, increasing from fewer than ten food plant species in the earliest (lowest) levels to over 30 species in the latest levels. Clearly, later inhabitants of the cave used a greater variety of plants as food than earlier inhabitants did.
Which of the following, if true of the cave, most weakens the argument?
(A) Some of the plant species found in the earlier (lower) levels of habitation are not found at all in the later (upper) levels of habitation.
(B) The remains of some plant species, such as squash and chili peppers, show changes from the middle to the later (upper) levels that indicate domestication.
(C) At certain points during the period from 9,000 to 500 years ago, the cave was abandoned for a time and later reoccupied by people who were probably of a different culture than the earlier inhabitants
(D) Virtually all the plant remains found at earliest (lowest) levels of habitation are tough fibers that are relatively resistant to decomposition.
(E) The total volume of food plant remains found in the earlier (lower) layers was greater than that found in the later (upper) layers.
參考答案:D
文本大意為:中美洲的一個洞穴在之前的9000 至500 年間,有人類居住。考古學(xué)家發(fā)現(xiàn)其中不同時期遺留下的食物類植物。其中早期的有不到十種,后期有超過三十種。顯然,后期居住者的食物種類更多。
題目要求選擇一個選項,削弱文本論證。選項D 符合:發(fā)現(xiàn)的早期食物幾乎都是不容易被分解的莖類植物。也就是說,其他類型的食物可能因年代久遠都已經(jīng)被分解了,考古學(xué)家無法發(fā)現(xiàn),故無法判斷前期食物種類就比后期少。

Avionics is a portmanteau word meaning “aviation electronics.” It is a term that has evolved over the last 40 years as airplane instrumentation has evolved from mostly mechanical to largely electronic. Today, avionics makes up the large part of the cost of any aircraft. Guidance and navigation systems are integrated. Communications includes public address systems for communicating with passengers, intercoms for communicating with flight crews, and radio or SatCom for communicating with ground personnel. In addition, planes today have weather radar, lightning detectors, automatic flight control systems, and collision-avoidance systems. All of these systems must work in tandem in order for the plane to fly.
Select one answer choice.
Which of the following inferences about avionics is best supported by the passage?
(A) Within a decade, passenger planes will take off and land without human intervention.
(B) Soon passenger planes will include features that now appear only on military planes.
(C) Just 40 years ago, there were no electronic devices on passenger airplanes.
(D) As avionics becomes more common, the cost of manufacturing planes will decrease.
(E) A glitch in a plane's electrical system may be the greatest danger in flight today.
參考答案:E. 文章大意:航空設(shè)備在過去40 年的發(fā)展過程中,逐漸由大部分為航空機械設(shè)備發(fā)展成大部分為航空電子設(shè)備。故如果出現(xiàn)電子差錯,可能導(dǎo)致大的危險,E 選項正確。

Many shipwrecks dating from the period between A.D. 300 and 600 have been discovered in the Ramian Sea. Well over half of those ships were carrying cargo stored in large ceramic jars, many of which were preserved largely intact on the ocean floor. During that period, such jars carried only liquid. Therefore, liquid cargo was probably carried by a majority of the cargo ships that navigated the Ramian Sea during that period.
文章大意:很多公元前300 至600 年的遇難船只在Ramian 海域被發(fā)現(xiàn)。一半以上的船運載的是裝在陶瓷罐里的貨品。這些大部分在海底保存完好。在那個時期,這種罐子只裝液體。因此,當(dāng)時航行在Ramian 海域的大部分貨船運送的是液體貨物。
The force of the evidence cites in the passage is most seriously weakened if which of the following is true?
A. For ships on the Ramian Sea during the period, a full load of liquid cargo stored in large ceramic jars was not likely to be significantly heavier than a full load of other kinds of cargo that were typical of the period.
B. There are no surviving records dating from the period that detail specific cargoes shipped across the Ramian Sea.
C. The ratio of liquid to solid cargo shipped across the Ramian Sea did not vary significantly over the period.
D. The presence of a sizable quantity of large ceramic jars on the ocean floor is so visually striking that a shipwreck of a ship carrying such jars is more likely to be noticed and reported than are shipwrecks of ships carrying other cargoes.
E. During the period, grain and other solid cargo was shipped across the Ramian Sea in containers made from material other than clay.
參考答案:D 載有陶瓷罐的遇難船只比裝有其他貨品的遇難船只更容易被人發(fā)現(xiàn)。由此會弱化大部分船只裝在液體的結(jié)論。

The Canadian elk has traditionally been limited in its geographic range by the presence of elderberries, its primary source of food, which only grow up until a certain point in the tundra. A recent rise in temperatures, however, has seen a spread in the growth of elderberries northwards into the tundra. Therefore, the overall range of the Canadian elk can be expected to increase.
Which of the following, if true, best casts doubt on the argument?
A. In addition to elderberry, the Canadian elk also consumes loganberries, which are expected to also begin growing at more northerly latitudes.
B. During the summer months, many Canadian elk are hunted both for sport and for their meat.
C. The grizzly bear, the Canadian elk’s primary predator, has also started moving north into the tundra.
D. The permafrost, the region above the tundra, in which the temperatures never reach above freezing, will unlikely see elderberry growth.
E. Increasing temperatures have created conditions too warm for elderberry growth in the southern half of the Canadian elk’s traditional territory.
答案:E。E 選項表明在elk 的傳統(tǒng)生活領(lǐng)域,elderberry 因為天氣原因不再生長,故Canadian elk 的生活區(qū)域?qū)币,而不會擴大。

After examining the bodies of a dozen beached whales and finding evidence of bleeding around the animals’ eyes and brains as well as lesions on their kidneys and livers, environmental groups fear that the Navy’s use of sonar is causing serious harm to marine animals. A leading marine biologist reports that sonar induces whales to panic and surface too quickly, which causes nitrogen bubbles to form in their blood.
The argument above relies on which of the following assumptions?
A. Marine biologists have documented chat other marine animals, including dolphins and sea turtles, have exhibit kidney and liver lesions.
B. No studies have been conducted on the possible detrimental effects of sonar on marine animals.
C. Whales in captivity panic only when exposed to man-made, rather than natural, sound waves.
D. The presence of nitrogen bubbles in the blood has been demonstrated to cause damage to various internal organs.
參考答案:E.
