GWD 6 sloth bear

rongrong518

问题11, which of the following, if true, would most weaken the author's augument in lines 18-26.

下面是18-26的原文: furthermore, the daily movements of sloth bears and american black bears - which are similar in size to sloth bears and have similar-sized home ranges - reveal similar travel rates and distances, suggesting that if black bear cubs are able to keep up with their mother, so too should sloth bear cubs.

C some sloth bears have home ranges that are smaller in size than the average home ranges of black bears.

D the locomotion of black bears is significantly more efficient than the locomotion of sloth bears.

答案是D, 但我做题时, 见问的是weaken, 马上选了C, 因为18-26原句中破折号间提到home ranges 的问题. locomotion 是在前句谈polar bear 的时候提到, 为什么这一题答案是D.

请指教. 祝考试顺利!!

are and have 代表客观事实，reveal 是推测=presumbly, 所以weaken 只能选推测的结果， travel rates and distances= locomotion

C some sloth bears have home ranges that are smaller in size than the average home ranges of black bears.

D the locomotion of black bears is significantly more efficient than the locomotion of sloth bears.

However, although polar bears’ locomotion

is similarly inefficient, polar bear cubs

walk along with their mother.  Further-

more, the daily movements of sloth

(20)      bears and American black bears—

       which are similar in size to sloth bears

       and have similar-sized home ranges—

reveal similar travel rates and distances,

suggesting that if black bear cubs are

(25)      able to keep up with their mother, so

too should sloth bear cubs.

Which of the following, if true, would most weaken the author’s argument in lines 18-26 (“Furthermore … sloth bear cubs”)?

              

1. Cub-carrying behavior has been observed in many non-myrmecophagous mammals.


2. Many of the largest myrmecophagous mammals do not typically exhibit cub-carrying behavior.


3. Some sloth bears have home ranges that are smaller in size than the average home ranges of black bears.


4. The locomotion of black bears is significantly more efficient than the locomotion of sloth bears.


5. The habitat of black bears consists of terrain that is significantly more varied than that of the habitat of sloth bears

Why not E? This is a supplementary information to weaken the argument, especially the rate and the distance.

I believe there is not a certain relationship between terrain and locomation that mainly has to do with whether it is necessary for sloth bears cubs to be able to keep up with their mothers.

Only can locomation be supposed to mainly effect the living habit of solth bears. This is what my understanding.

But the passage says "although polar bears’ locomotion is similarly inefficient". I think this is compared to black bear, so anything contradictory to this premise should be wrong.

Can anyone explain to me? Tks.

这句话说的是polar bears之间的比较，没有说到与black bear的比较

而且further more那句话说得是sloth bear 与black bear，不是polar bear

我也觉得是E，原文中说

if black bear cubs are

(25)      able to keep up with their mother, so

too should sloth bear cubs. 这是cubs（幼兽）之间的比较，首先原文中说道travel rate相似，楼上有人说reveal 是推测内容，D所以weaken了原文，但是D中如果母兽效率高幼兽效率也高，反之亦然，cubs都能跟上，没有weaken原文。倒是E中说地形的不同有可能造成cubs跟不上母兽。

bigtone

原文强调的是黑熊和sloth在每天走的物理距离的相似性，由小熊能跟上推出小sloth能跟上。
如果E说的是sloth面对的terrain复杂多变的话，E是个完美的答案；可是这里是black bear，所以小熊面对的困难更大，所以E是加强而不是削弱；
D确实不像答案，但是唯一可选的：
至少它强调了二者不同，而且说了黑熊有其他优势；难道locomotion和efficient这些前面讨论plolar bear时内容真的是用来迷惑的？确实BT的题。
