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.

_
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-

New employees at Avondale Industries’ unmanned systems production line in Denver, CO, participate in employee training under the direction of the training and development department, but the line managers conduct the actual training. During the last two trainings, the line managers cut the sessions short and explained that the employees would receive better training while working on the production line. The trainer responsible for the program understood the line managers’ viewpoint about developing skills used on the line but needed them to see that training should provide more than just developing those specific skills. Which of the follow statements best explains why training should provide a longer-term view than just teaching line workers the skills needed to perform satisfactorily in their current jobs?
Giving line workers expanded training helps them understand more than specific skills; it also helps them become more confident contributors.

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_forwardA chemist working as a safety inspector finds an unmarked bottle in a lab cabinet.

Calculate the density of the liquid. Round your g. cm answer to 3 significant digits. yes Given the data above, is it possible to identify the liquid? no glycerol carbon tetrachloride pentane If it is possible to identify the liquid, do so. tetrahydrofuran acetonearrow_forward
