III. Read the passage given below.
Decision-making is a very vital part of our lives. This is because what we are today is largely a result
of the decisions we took in the past. Similarly, whatever happens tomorrow will be a
result of the decisions we take in the present. It is not possible to reverse the wrong decisions
taken in the past but it is possible to train ourselves into becoming a good decision-maker for
the future. If we don’t, we’ll end up doing what we’ve always done and thus get what we’ve always
got.
All sorts of decisions big or small, relevant or irrelevant, conscious or unconscious punctuate
our lives. Those who avoid taking a decision leave everything to chance and float along life
with a what will be, will be attitude. To enhance our decision-making, we must, first of all,
gather as much information as possible about the issue before we make our decision. We
might be heading for a failure if our decisions are based on half-baked information. If you
have a set of guiding principles for your life, decision-making becomes a lot easier.
Sometimes decisions are very difficult to make, especially when the odds seem to be against
us. In this case, giving ourselves a little time to decide wouldn’t be a bad idea at all.
On the basis of your reading of the passage above complete the following sentences.
a) The course of our life is largely determined by our
i. actions
ii. decisions
iii. interests
iv. plans
b) The first step towards decision-making would be to
i. think too much
ii. understand our needs
iii. collect maximum information about the matter
iv. get half baked information
c) Decision-making may be futile if
i. the information is not sufficient
ii. our interests differ
iii. objectives are not clear
iv. we are indecisive
d) If things are not in our favour, we can
i. work hard
ii. leave the situation
iii. give some time to ourselves
iv. float with the situation
e) to enhance means
i. to understand
ii. to decrease
iii. to stabilize
iv. to boost
