10. Michelangelo's sixteenth-century Sistine Chapel paintings are currently being restored. A goal of the restorers is to uncover Michelangelo's original work, and so additions made to Michelangelo's paintings by later artists are being removed. However, the restorers have decided to make one exception: to leave intact additions that were painted by da Volterra.
Which one of the following, if true, most helps to reconcile the restorers' decision with the goal stated in the passage?
(A) The restorers believe that da Volterra stripped away all previous layers of paint before he painted his own additions to the Sistine Chapel.
(B) Because da Volterra used a type of pigment that is especially sensitive to light, the additions to the Sistine Chapel that ad Volterra painted have relatively muted colors.
(C) Da Volterra's additions were painted in a style that was similar to the style used by Michelangelo.
(D) Michelangelo is famous primarily for his sculptures and only secondarily for his paintings, whereas da Volterra is known exclusively for his paintings.
(E) Da Volterra's work is considered by certain art historians to be just as valuable as the work of additions to Michelangelo's work.
这里的additions指什么呢？是不是说有些画家在M的画上还会再画些东西。那为什么不连daVo的也一起去除呢? 这样才符合uncover原著的目的呀。
14. Cafieine can kill or inhibit the growth of the larvae of several species of insects. One recent experiment showed that tobacco hornworm larvae die when they ingest a preparation that consists in part of finely powdered tea leaves which contain caffeine. This result is evidence for the hypothesis that the presence of non-negligible quantities of caffeine in various parts of many diverse species of plants is not accidental but evolved as a defense for those plants.
The argument assumes that
(A) caffeine-producing plants are an important raw material in the many facture of commercial insecticides
(B) caffeine is stored in leaves and other parts of caffeine-producing plants in concentrations roughly equal to the caffeine concentration of the preparation fed to the tobacco hornworm larvae
(C) caffeine-producing plants grow wherever insect larvae pose a major threat to indigenous plants or once posed a major threat to the ancestors of those plants
(D) the tobacco plant is among the plant species that produce caffeine for their own defense
(E) caffeine-producing plants or their ancestors have at some time been subject to being led upon by creatures sensitive to caffeine
什么逻辑思路？
