Hi all,
I am working on CR Methods. I will post all what I will learn in this thread. If you have something to add then you are welcome. My learnings for the day:
1. Must be true/Inference/Conclusion CR: You have to consider whatever stated in the stimulus as true.
Correct choices can be:a. Paraphrased of some part or entire stimulus
b. Combination of two or more premises
Incorrect choices can be:a. Could be true or Likely to be true choices
b. Exaggerated/Extreme case answers
c. New information (not explicitly mentioned in the stimulus) containing choices
d. Shell game (an idea, in one of the choices, similar to the one mentioned in the stimulus, but in a modified form to make it attractive choice. This will be a Trap)
e. Choices mentioning the opposite answer (opposite to the stated facts in the stimulus). For example, stimulus shows case >>> effect while the choice says effect >>> cause.
f. Choices in Reverse order (rearrangement of some term in the answer choices which are also mentioned in the stimulus). For example,
Many politicians are having
some type of security gadgets.
While the choice says:
Some politicians are having
many types of security gadgets.
Following is an example where some of the above correct and incorrect choices are discussed:
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. [No mention of such things.
It's a New Information Inclusion case.Incorrect]
(B) Radiocarbon dating can be corroborated by glacial evidence. [
Reverse order case as per stimulus. Incorrect]
(C) Similarities between prehistoric and contemporary climates do not exist. [No mention of similarities in the stimulus and this is
extreme generalization. Results can be found by comparing samples.
Incorrect case]
(D) Pollen deposition is a fairly continuous process. [No mention is the stimulus.
Incorrect]
(E) Certain flora are reliably associated with particular climatic conditions. [
Correct] Read the following premises in support of this:
1. 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.
2. 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.
I hope my OA is correct.
