BG:Carl is said as an incompetent detective
reason:solve smaller percentage of the cases than other detective
conclusion: Carl is incompetent

weaken:
1 out of 25 can be declared as incompetent
solve case is the only one indicator?

A:
correct. becase most difficlut cases require lot of time and very difficlut. Others may not finish the same way as Carl

B:
Not related. good relationship with neighborhood doesn't help to indicate if Carl is competent

C:
Not related. Other detective relies on the source of Carl doesn't help the case.  答案说是strengthen （This is an Opposite answer that strengthens the claim that
Carl is incompetent by showing that Carl was not deprived of certain resources
for solving cases.）

D:
Strengthen, other city's poor record helps the conclusion  

E:
Not related. Others get promoted doesn't help the case. But it will help they tell us Carl cannot be promoted because of his incompetence.（标准答案说是想得太多了。This answer goes beyond the scope of the argument by
discussing the promotions of other officers. These promotions do not impact
Carl’s job and no information is given about Carl’s promotions. If you are
thinking that perhaps Carl’s poor performance is a result of dissatisfaction over
the promotions of others, then you are assuming too much.）
