### HideShow timer Statistics

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

Is it E?

If they can derive the climate conditions from the pollen trapped in Finland by comparing with the pollen from Antartica, at least it must be true that the pollen are associated with that climate.

D looks good to me..
If pollen disposition is not a continuous process and say it happens only in autumn then how would scientists determine about the other weather conditions.

I'm going with (E), since the whole discussion is irrelevant if (E) is not true. (D) has validity, but I believe that it requires reading into the question too much.

I choose (E).

D distorts the evidence in the passage. Regardless of whether or not pollen distribution is a continuous process, it is the "density" of the pollen trapped at the time which gives researchers a solid basis of comparison.

(E) is best because it is a logical statement backed up by the passage. Clearly, only the hardiest and most resilient plants could survive during a global ice age. Can`t imagine palm trees flourishing 14,000 years ago.

Great CR Vivek. Source?

flora
Plants considered as a group, especially the plants of a particular country, region, or time.

This is the dictionary meaning of flora.

Will go with E.

Close call between D and E but there is no mention of the pollen formation process.
The author mentions that pollen trapped in galcial ice can be used to know the climatic conditions. If pollen was a continous process how will you determine which climate it is denoting.
Whereas specific plants give out pollen in certain climatic conditions.
