### HideShow timer Statistics

A 20 percent decline in lobster catches in Maine waters since 1980
can be justifiably blamed on legislation passed in 1972 to
protect harbor seals. Maine's population of harbor seals is now
double the level existing before protection was initiated, and these
seals are known to eat both fish and lobsters.

Which of the following, if true, would most seriously weaken the

argument above?

A Harbor seals usually eat more fish than lobsters, but the
seals are natural predators of both.
B Although harbor seals are skillful predators of lobsters,
they rarely finish eating their catch.
C Harbor seals attract tourists to Maine's coastal areas, thus revitalizing the local economy.
D Authors of the 1972 legislation protecting harbor seals
were convinced that an increase in that animal's numbers would not
have a measurably negative impact on the lobster catch.
E The record lobster harvests of the late 1970's removed large
numbers of mature lobsters from the reproductive stock.

E.

A: still eat lobsters could still explain decline
B: still kill the lobsters. this is just a silly answer choice
C: irrelevant
D: doesnt mean they werent wrong. this doesnt really weaken that much.

E is best b/c if mature lobsters gone then no lobsters to reproduce for awhile and perhaps a lot of baby lobsters die off very easily. etc...

this is def it.

For me the argument - a blame on legislation to protect seal population...

There is nothing to blame here.. as the economy did grow because of tourism. It is something good and to be happy about..

'C' ..

moreover the original stem doesn't highlight any harms caused because of seal's over population

Seems like a straight E to me.
