A word of Caution: Speed with Accuracy
Capacity to read fast is definitely an advantage, though you should bear in mind that
reading for speed alone could be counter-productive. Speed reading is not the ultimate
aim. The aim is to answer the questions correctly and to make the fullest use of your
capacity.
The need for assimilation:
Reading is assimilation – learning – and all learning is a
digestive process. On the face of things, it seems that there is a trade–off between
speed and assimilation – if the reader goes twice as fast he assimilates half as much –
but it need not be so.
Assimilation is somewhat faster if you are able to relate your knowledge of the subject to the
material you are reading
.
This is not to say that if you are not familiar with the subject
matter you will not be able to assimilate well. You may just take a little longer and this
will not reduce your speed drastically.
Key Point:
Assimilation is measured by the quality of retention of information and the
ability to recall relevant information. If you try to look at words rather than look for their
meaning, you are being passive instead of being proactive. This approach may increase
your speed but do nothing for assimilation. It is therefore a question of striking the right
balance between speed and comprehension and reading flexibly.
RC tests your ability to answer the questions correctly rather than your ability to read faster.
Hence,
regardless of how fast you can read a given text, it is the accuracy of the answers to the
questions that matters in the test. Even if your reading speed is just average, you can
maximize the accuracy by using appropriate techniques. Cracking the RC is a right
combination of speed and technique.
What do the RC Questions Measure
Reading Comprehension questions measure your ability to understand, analyze, and
apply information and concepts presented in written form.This section evaluates the
following abilities:
Understanding words and statements in reading passages:
Questions of this type test your
understanding of and ability to comprehend terms used in the passage and your
understanding of the English language.
Understanding the logical relationships between
significant points and concepts in the reading passages:
Questions of this type ask you to
determine the strong and weak points of an argument or to evaluate the importance of
arguments and ideas in a passage.
Drawing inferences from facts and statements in the reading passages:
Questions of this type
ask you to consider factual statements or information and, on the basis of that
information, reach a general conclusion.
17
_
Understanding and following the development of quantitative concepts as they are presented in
verbal material:
Questions of this type involve the interpretation of numerical data or the
use of simple arithmetic to reach conclusions about material in a passage.
Consider the following passage:
Producing and using biodiesel, a fuel derived from cultivated rapeseed, causes 35
percent less air pollution per gallon than does producing and using regular diesel fuel.
The government plans to reduce diesel-related air pollution over the next decade by 25
percent, so replacing regular diesel with biodiesel would seem to be the obvious
solution. Unfortunately, the greatest possible production of biodiesel would amount to
only one percent of all diesel fuel to be produced during the next 15 years.
Q. The passage is structured to lead to which of the following as a conclusion?
.
(A) The use of biodiesel will increase by less than one percent over the next 15
years.
.
(B) During the next 15 years, the production of biodiesel will be increased as fast as it
is possible to increase it.
.
(C) During the next 15 years, it will be impossible, just by switching to biodiesel, to
meet the government's stated goal with respect to reducing air pollution.
.
(D) Fifteen years from now, the air pollution caused by the production and use of one
gallon of regular diesel fuel will be far less than it currently is.
.
(E) There will be no significant year-to-year increase in the amount of regular diesel
fuel used
during the next 15 years.
How to answer the question:
What are the “government’s plans”? What is the “obvious solution”?
Reduce air pollution by 25% over the next decade Replace regular diesel with biodiesel
What is “unfortunate”?So meeting the targets is “impossible” (C).
The greatest possible production of biodiesel would amount to only one percent of all
diesel fuel

Lecture – II
Read for the Main Idea
Every discussion, every article, every write-up has a main idea. Likewise every RC
passage has a main idea. The main idea is the nucleus of the passage. Most of the
questions based on the passage reading not only concatenate, they also revolve around
the main focus of the passage. So it is very important to catch the main idea of the
passage to be able to get most of the answers right.
How to get the main idea of the passage? The main idea is the idea that occurs
repeatedly in the passage
.
So look for a repetitive words or phrases in the passage.
The
first sentence of a paragraph should always be read carefully
since it is so often the key to
understand the entire paragraph.
Consider the following passage:
One is faced then with the conflicting claims of Picasso and Kandinsky to the position of
true leader of non- representative art. Picasso's admirers
hail
him, as a visual musician.
The methods and ideas of each rival are
so different that the title cannot be accorded to both. In his book, Kandinsky states his
opinion of Cubism and its fatal weakness, and history goes to support his contention.
The origin of Cubism in Cezanne, in a structural art that owes its very existence to
matter, makes its claim to pure emotionalism seem
untenable
. Emotions are not
composed of strata and conflicting pressures.
What is the
thematichighlight
of the passage?
.
(A) The author agrees with Kadinsky’s criticism of cubism.
.
(B) The author validates the claim of Kadinsky to the position of true leader of non-

representative art.
.
(C) The author is trying to assess as to who, between Picasso and Kadinsky, can be
the true protagonist of non-representative art.
.
(D) Cubism is a non-representative art; but Kadinsky doesn’t agree with this
assertion.
.
(E) Kadinsky is right in pointing out the fallacy in the claim to pure emotionalism in
Cubism.
Now, ask yourself: What's the gist of the argument?The author talks about the
conflicting claims of Picasso and Kandinsky.What are the conflicting claims about?They
are about cubism. The author states that “history goes to support his (Kandinsky’s)
contention” and goes on to add that “its (cubism’s) claim to pure emotionalism seem
untenable”By quickly determining the topic and scope while reading, we can easily
deduce what the author is writing and why. Actively reading passages can save a
considerable amount of time once you get to the questions.
19
_
Once you’ve got the main idea, it isn’t necessary to pay a lot of attention to the other
sentences in the paragraph. For example, you would probably notice that while the
second sentence included some specific FACTS, it adds nothing to your understanding
of the main point of the paragraph. Later, if you are asked a specific question about this
FACT, you can go back and find the answer; it will still be there.
Don’t Be Dramatic
The test makers realize that people have different points of view. They don’t want to be
dogmatic, saying, ”This is the only way. Do not argue!” They do want to leave some
space for personal interpretation. So if you have two answers, choose the more
moderate one.
For example:
Two answer choices:
.
(A) The author hates discrimination.
.
(B) The author is saddened by discrimination and tries to go to its root levels. Choice
(B) is kinder and gentler and would therefore, be the more probable answer
Trips and traps for main idea Questions
Always remember that there need not be patently wrong answer options. The examiner
may set a trap for you by presenting other than the best options as the right answers.
Be on the look out for such traps. Some of these could be:
Disputable statements:
Authors of passages will never use strongly negative statements
for other people or ideas.
Extreme statements:
A moderately worded statement is invariably more likely to be the
right answer than a rather extreme and one sided statement.
Direct repetitions (same language):
Language directly picked up from the passage is more
likely to be a trap. The right answer will possibly lie hidden in a heap of indirect
references.
Supporting Idea(s):
The passage may have several supporting ideas, apart from one
main idea. Don’t fall for the supplementary idea(s).
Half truths:
Don’t fall for an answer that may appear to be true, but may have a
word/phrase that may render it false.
‘True statement’:
Again don’t jump at an answer simply because it appears to be true as
per the passage. Always proceed through the process of progressive elimination (POE).
You need to be careful about many of the above traps in case of other question types
also.
20
_
Key Point:
The primary purpose of the passage, title, central idea etc is one, which is
mentioned repeatedly in the passage. At times there is a strong temptation to choose an
answer which has been mentioned only once or has been touched obliquely in the
passage. Avoid these traps and reject these choices in favour of the one, which is
referred to repeatedly in a major part of the passage. Again, although the main
idea/theme/title of the passage and the author’s purpose could, in most cases, be the
same, yet in some cases, there could be a fine line of distinction between the two. The
author’s purpose may not be expressly stated in the passage, though it can always be
inferred.

PR However, you can use this plot (an example of the law of corresponding states) to calculate the molar volume (V) of ammonia at a temperature and pressure of interest. What information do you need in order to do this? O The critical temperature and pressure for ammonia. The standard molar Gibbs energy for ammonia. O The normal boiling point for ammonia. O The vibrational spacing in ammonia.arrow_forwardA chemist working as a safety inspector finds an unmarked bottle in a lab cabinet. A note on the door of the cabinet says the cabinet is used to store bottles of diethylamine, pentane, acetone, carbon tetrachloride, and tetrahydrofuran. The chemist plans to try to identify the unknown liquid by measuring the density and comparing to known densities. First, from her collection of Material Safety Data Sheets (MSDS), the chemist finds the following information: liquid density g 0.71 mL diethylamine olo Ar pentane 0.63 mL g 0.79 mL acetone g 1.6 mL carbon tetrachloride g 0.89 mL tetrahydrofuranarrow_forwardChemistry Hello!
