One of the more reliable methods of determining regional climatic conditions in prehistoric periods is to examine plant pollen trapped in glacial ice during ancient times. By comparing such pollen samples with spores taken from modern vegetation, scientists can figure out approximately what the weather was like at the time of pollen deposition. Furthermore, by submitting the prehistoric samples to radiocarbon dating techniques, we can also determine when certain climatic conditions were prevalent in that portion of the globe.

Which one of the following may be inferred from the information in the passage?

(A) The earth has undergone several glacial periods.
(B) Radiocarbon dating can be corroborated by glacial evidence.
(C) Similarities between prehistoric and contemporary climates do not exist.
(D) Pollen deposition is a fairly continuous process.
(E) Certain flora are reliably associated with particular climatic conditions.

welcome rahulraoo with your super tough CRs

My pick is:
A.

by submitting the prehistoric samples to radiocarbon dating techniques, we can also determine when certain climatic conditions were prevalent in that portion of the globe.

seems to indicate that we can get multiple pollen samples, which are trapped during several glacial periods.

assumption: glacial ice is only formed during glacial periods

B. never suggested

C. weaken the argument

D. another good candidate. however, its so continuous it will be difficult to tell exactly when climatic conditions changed?

E. not necessarily implied by the argument

I think D is correct. 'coz unless it is a continous process it would be hard to predict climatic conditions. Spread has to be continous to link it to the regional climate.

What is the OA?

Hmm toughie...between b and E...

will go with E...cause the stem says one of the more better"reliable" method is to use pollen examanation blah ..blah...clearly infers E...that flora (another word for Pollen)...are a reliable way to do blah blah..

Posting here after a looong time!

I'll go with D.

I don't like E because it uses the word 'reliably' while scientists can only determine it 'approximately'. Weak one but something's got to go!
