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
