标题: 各位大侠，偶有题目请教！
1：Over the last century, palentologists have used small differences
between fossil specimens to classify triceratops into sixteen species.
This classification is unjustified, however, since the specimens used
to distinguish eleven of the species comes from animals that lived in
the same area at the same time.

Which of the following, if true, would enable the conclusion of the argument to be properly drawn?

A: Not every species that lived in a given area is preserved as a fossil

B: At least one individual of every true species of triceratops has
been discovered as a fossil specimen

C: No geographical area ever supports more than three similar species at the same time

D: In many species, individuals display quite marked variation.

E: Differences between fossil specimens of triceratops that came from
the same area are no less distinctive than differences between
specimens that came from different areas.

2: Which of the followin, if true, is the most logical completion of the argument below?

The tax system of the RG encourages borrowing by granting its taxpayers
tax relief for interest paid on loans. The system also discourages
saving by taxing any interest earned on savings. Nevertheless, it is
clear that PG's tax system does not consistently favor borrowing over
saving, for if it did, there would be no---

答案是: tax relief in PG for those portions of a taxpayer's income, if
any, that are set aside to increase that taxpayer's total savings.

谢谢各位大侠牛人帮偶解释一下拉：）

Q1: C.

If C is true, then from "since the specimens used to distinguish eleven of the species comes from animals that lived in
the same area at the same time" one can draw conclusion that "classification is unjustified".
