Sneha333
Please explain this..How can we assume about the place where sandstone was found was the place of origin for choice D.
Sneha333, A good thought!
However, even if one assumes that the place where sandstone was found was
NOT the place of origin for choice D, i.e.,
Let's say: The place of Origin - PofO
The place of Discovery - PofD
The sandstone could STILL be
transferred from PofO to PofD because of
natural events such as floods, landslides, etc.
- A possibilityEven if we
assume the above case(
PofO != PofD ), it would
NOT aid us in
weakening the conclusion.
Conclusion: Marks are traces of GP(geological processes) rather than of Worms.
The geologists are concerned about the causes which could have led to those marking.
They are contemplating the
probable origins of the marks. It does
NOT matter
whether sandstone's Discovery was the same place as its Origin.
To answer this:Quote:

Speaking for Option-D, I think the
thought process behind this case(
PofO != PofD ) was to look for
an alternate cause such as:
1) the marks could have happened in the PofO rather than in PofD. &
2) the reason for those marks in PofO should NOT be GP(geological processes) - These things could have been true.
However, a
lot of further assumptions are involved in reaching this aspect, which would
NOT be
correct unless backed by a
coherent answer choice.
TakeAway: A
correct weakener:
1) Should be a piece of NEW information. - Not already stated/inferred.
2) Needs to raise a DOUBT on the conclusion. It need NOT necessarily destroy the conclusion.
