关于OG721题的疑惑

士多啤梨www

OG721题是关于 骨骼被埋在一起vs是否是domesticated的题目。
这个题最终的答案我懂，但是看og解析的时候，它给出来了几个削弱的方向，其中有一个是：
The argument could also
be weakened by evidence that the two skeletons were
not actually buried together around 9,500 years ago.

这个相当于直接否定了题干的前提。所以我的问题是，削弱题可以直接削弱前提是吗？我理解只能根据前提→结论的gap/漏洞去削弱呢..

完整的题目和解析如下：
721. Archaeologist: Researchers excavating a burial site in Cyprus found a feline skeleton lying
near a human skeleton. Both skeletons were in the same sediment at the same depth and
equally well‐preserved, suggesting that the feline and human were buried together about
9,500 years ago. This shows that felines were domesticated around the time farming began,
when they would have been useful in protecting stores of grain from mice.
Which of the following, if true, would most seriously weaken the archaeologist’s argument?
A. Archaeologists have not found any remains of stores of grain in the immediate vicinity
of the burial site.
B. The burial site in Cyprus is substantially older than any other known burial site in
which a feline skeleton and a human skeleton appear to have been buried together.
C. Paintings found near the burial site seem to show people keeping felines as domestic
companions, but do not show felines hunting mice.
D. In Cyprus, there are many burial sites dating from around 9,500 years ago in which
the remains of wild animals appear to have been buried alongside human remains.
E. Before felines were domesticated, early farmers had no effective way to protect stores
of grain from mice.
Argument Evaluation
Situation A human skeleton and a feline skeleton were apparently buried together in
Cyprus about 9,500 years ago.
Reasoning What would most strongly suggest that the skeletons do not show that felines
were domesticated around the time farming began? The argument implicitly
assumes that farming in Cyprus began around 9,500 years ago, so evidence
against that assumption would weaken the argument. The argument could also
be weakened by evidence that felines were domesticated much earlier, that the
feline skeleton was not from a domesticated cat, or that the two skeletons were
not actually buried together around 9,500 years ago.
A. Even if archaeologists searched for evidence of a grain store, the fact that no such
evidence was found near the burial site is at best only weak evidence that no grain
store existed there or slightly farther away.
B. The lack of corroborating evidence from other burial sites would weaken the argument
slightly but would still be compatible with the hypothesis that this site revealed one of
the very first burials of a domesticated cat.
C. This would cast doubt on the hypothesis that cats were domesticated mainly to protect
stores of grain, but not on the argument’s conclusion that cats were domesticated
around the time farming began.
D. Correct. If many wild animals were buried alongside humans in Cyprus around
9,500 years ago, then the feline skeleton is just as likely to be that of a wild animal
than that of a domesticated cat.
E. Since this would provide an additional reason why early farmers might have
domesticated the local cats, it would strengthen rather than weaken the argument.
The correct answer is D.

只要不是事实都可以否定，比如这里的事实是人和猫的骨头一起被发现了，但是9500年前是不是一起埋在这里的并不知道，也有其他可能，因此解释里的说法也是质疑gap
