LSAT interesting CR

Sociologist: Climate and geology determine where human industry can be established. Drastic shifts in climate always result in migrations, and migrations bring about the intermingling of ideas necessary for rapid advances in civilization.

The sociologist’s statements, if true, most strongly support which one of the
following?
(A) Climate is the primary cause of migration.
(B) All shifts in climate produce a net gain in human progress.
(C) A population remains settles only where the climate is fairly stable.
(D) Populations settle in every place where human industry can be established.
(E) Every migrations accompanies by rapid advances in civilization

OA to Follow

[Retake_GMAT]

IMO B

If DCS (Drastic climatic Shift) , then Migration

If Migration, then human advance.

Hence, DCD causes human advance

[yashesha]

Imo E

[MCapri]

Not sure but IMO D...can explain if the answer matches the OA. OA pls

[ram_ram]

IMO B..

E specifies that migration is accompanied by advancement in civilazation.But tha author specifies that Climate->migration->advancement.But migration could also be caused by some other factors and hence migration may not lead to civilization advancement.

D specifies Populations settle in every place where human industry can be established whereas the author specifies it in the other way round(the industry is set up based on the climate and civilisation)

[vivek_sain]

IMO E

I think B cannot be the answer because:
(B) All shifts in climate produce a net gain in human progress.---argument states only drastic changes in climate cause migration

[Praso]

IMO is C because, Drastic shifts in climate always result in migrations. And C clearly states that.

[ranjeet_1975]

I come to either A or C. But agree with Praso and opted C

[borntorun]

IMO C ... question tests conditional reasoning ...

DSC ---------->M

OA to Follow

IMO C

1st causal conclusion DSC ----> Mig )
Apply the principle , No cause then no effect

No drastic changes in climate ( climate is fairly stable ) ----> No migration ( population remains settled )
which is option C

2nd causal conclusion : ( Mig---> human advances )


Option E is wrong because

Every migration leads to human advances, why so?
maybe some migrations may not lead to human advances
It uses principles of alternative causes.

Thanks
