Balance is particularly important when reporting the background of civil wars and conflicts. Facts must not be deliberately manipulated to show one party in a favorable light, and the views of each side should be fairly represented. This concept of balance, however, does not justify concealing or glossing over basic injustices in an effort to be even-handed. If all the media were to adopt such a perverse interpretation of balanced reporting, the public would be given a picture of a world where each party in every conflict had an equal measure of justice on its side, contrary to our experience of life and, indeed, our common sense.
Which one of the following best expresses the main point of the argument?
(A) Balanced reporting presents the public with a picture of the world in which all sides to a conflict have equal justification.
(B) Balanced reporting requires impartially revealing injustices where they occur no less than fairly presenting the views of each party in a conflict.
(C) Our experience of life shows that there are indeed cases in which conflicts arise because of an injustice, with one party clearly in the wrong.
(D) Common sense tells us that balance is especially needed when reporting the background of civil wars and conflicts.
(E) Balanced reporting is an ideal that cannot be realized, because judgments of balance are necessarily subjective.

答案选B，不明白为什么

11. Recently discovered fossil evidence casts doubt on the evolutionary theory that dinosaurs are more closely related to reptiles than to other classes of animals. Fossils show that some dinosaurs had hollow bones—a feature found today only in warm-blooded creatures, such as birds, that have a high metabolic rate. Dinosaurs had well-developed senses of sight and hearing, which is not true of present-day cold-blooded creatures like reptiles. The highly arched mouth roof of some dinosaurs would have permitted them to breathe while eating, as fast-breathing animals, such as birds, need to do. Today, all fast-breathing animals are warm-blooded. Finally, fossils reveal that many dinosaurs had a pattern of growth typical of warm-blooded animals.
The argument in the passage proceeds by
(A) attempting to justify one position by demonstrating that an opposing position is based on erroneous information
(B) establishing a general principle that it then uses to draw a conclusion about a particular case
(C) dismissing a claim made about the present on the basis of historical evidence
(D) assuming that if all members of a category have a certain property then all things with that property belong to the category
(E) presenting evidence that a past phenomenon is more similar to one rather than the other of two present-day phenomena

答案是E，可我觉得是D，求教

第一题，LZ要首先要把握本文的用意，也就是Main Point，就是在解释什么是Balance，然后要注意This concept of balance, however, does not justify concealing or glossing over basic injustices in an effort to be even-handed.这句话，说concealing或glossing over 不公正都是不对的，言下之意，就是要正确表述“不公正” 就是B里的requires impartially revealing injustices。 B里的后半句是题干描述的前半部分。

第二题题目问的是题干是如何进行的，题干一直是在Present 没有assume，而且D的表述太绝对了，all 这样的单词出现一般都太绝对化，不会对的~ E还体现了对比的东西，与题干也更接近。
