English Cloze Question-SBI PO 2015 Prelim

In the given passage, there are blanks, each of which has been numbered. Against each five words are suggested, one of which fits the blank appropriately. Find out the appropriate word in each case.

A strong economy would improve livelihoods and give hope for the future, but the lack of reliable electricity in the country has contributed to holding back prosperity. Over the past five years, GDP growth has averaged 3 percent, too …..(1)….. to fight poverty and create jobs. Demand for power outstrips what the country can produce and …… (2)…… . Planned and unplanned electricity outages of 12 to 16 hours daily nationwide …… (3)…… business, aggravate unemployment and spark angry protests. The country has ……(4)…… energy resources- an estimated 186 billion tons of coal, over 100,000 megawatts of hydro potential and wind potential of up to 3,46,000 megawatts. But the technology and investment to ……(5)…… these resources are limited. An overreliance on imported fuel has exposed the country to high oil prices and there isn’t enough money to keep the system – a mix of private and state-run enterprises running or to fix faulty infrastructure that leaks electricity. A resolution of power crisis is thus very critical to the survival of the country.

1. Over the past five years, GDP growth has averaged 3 percent, too …..….. to fight poverty and create jobs.

A. Much
B. Low
C. Required
D. Tough
E. Minimal

Answer: B. Low

Explanation:

In this sentence, the author argues that the GDP growth is not sufficient to fight poverty and create jobs. On the first look, options (a) much, (c) required and(d) tough don’t support his argument.

Then we left with option (b) low and option (e) minimal. Usually, students confuse between these two words while answering this question. So, let us define them and then decide which will suit this sentence.

Low- When we use low, we intend to say that something is lesser in volume, degree or content. For example- low pressure, low vision, low power, etc.

Minimal- On the other hand, minimal means the minimum or lowest possible amount of something. For example- The storm caused minimal damage in our city.

The argument in this sentence is not about what is the minimal value of GDP growth; it could be high or low.

Hence, the answer is (B) low

2. Demand for power outstrips what the country can produce and …………

A. Represent
B. Sufficient
C. Adequate
D. Amount
E. Deliver

Answer:  (E) Deliver

Explanation: In this sentence, the author is talking about electricity power which a country can produce and distribute or deliver.

3. Planned and unplanned electricity outages of 12 to 16 hours daily nationwide ………… business, aggravate unemployment and spark angry protests.

A. Run
B. Happens
C. Plans
D. Effect
E. Hurt

Answer: (E) Hurt

Explanation: Electricity outages of 12 to 16 hours nationwide means, there is no electricity for economic activities. So, it definitely hurt the business.

4. The country has ………… energy resources- an estimated 186 billion tons of coal, over 100,000 megawatts of hydro potential and wind potential of up to 3,46,000 megawatts.

A. Ample
B. Fix
C. Worst
D. Frequent
E. Paucity

Answer: (A) Ample

Explanation:

By any estimate, 186 billion tons of coal, over 100,000 megawatts of hydro potential and up to 3,46,000 megawatts wind potential is more than enough for any country to have in its energy pool. So, the option (c) worst; which means most degraded and (e) paucity (An insufficient quantity or number) do not fit the sentence.

The sentence does not indicate that the country has fix energy resource; it only provides an estimate. Therefore we could discard option (b). Fix.

Option (d) Frequent, means happening of something in a regular or short interval. So, We could easily omit this option.

We have an option (a) ample to represent the meaning for more than enough. Hence this would be our answer.

5. But the technology and investment to ………… these resources are limited.

A. Lack
B. Solve
C. Waste
D. Exploit
E. Advantage

Answer: (D) exploit

Explanation: Through this sentence, the author tries to explain that we have limited technology and investment capacity to utilize these ample energy resources.

Thus, the option which represents the word “utilize” will be our answer. By checking the dictionary I found that exploit also means utilize. Hence the correct answer is (D).

Other options are:

Lack – A state of absence of something.

Solve – To find  a solution

Waste – throw away or spend thoughtlessly.

Advantage- Benefit resulting from some event or action

What is the value of x in x^(1/3) – x^(1/9) = 60

Question:-

question-1

Explanation:

To simplify the equation, let us consider-

equation-1

We should also change the second term in y form-

equation-2

By putting the value of x from equation (1) in (2)

equation-3

Therefore,

equation-4

Now, to solve this polynomial equation we find the factors of the constant value 60 and substitute y with each factor for checking whether it makes the equation equals 0. Whichever factor will make the equation equals 0 will be the value of y.

So the factors of 60 are = 5×4×3

By substituting 5 in place of y,

equation-5

Now we check the next factor 4

equation-6

Hence, y = 4

Note: We could also do above calculations mentally to save the time.

From the equation (1) we know that

equation-7

Hence, the correct choice is option (b)

RA Question 1- Inequality Problem

Which of the following expressions will be true if the expression R > O = A > S < T is definitely true? 1) O > T 2) S < R 3) T > A 4) S = O 5) T < R

Solution:

Let me rewrite the expression:

R > O = A > S < T

To solve this type of question, it is better to check each option and test it for its truthfulness.

  1. O > T
    T > S < A = O
    T>S<O (because A = O)
    In the above expression, two symbols (>,<) are in opposite direction. According to inequality rules when two different symbols with equal priority make a relationship  with variables, the conclusion would be false.

    In this expression, S is less than T and it is also less than O. So, the relationship between T and O is undefined. T could be > or < or = with respect to O. To make it clear, suppose S is 30 and T is 50.

    S<T or 30<50.

    Now what would be the value of  O.

    O could be 40, greater than S but less than T.
    O>S; T<O

    O could be 50, which is greater than S but equals to T.
    O>S; O=T

    O could be 60, which is greater than S and also greater than T
    O>S; O>T

    Hence, conclusion O> T is false.

  2. S < R
    S< A = O < R
    S<A<R

    S is less than A which is equals to O. A and O both is less than R,

    Hence, S < R. It’s true.There is no need to solve further as we get the answer (2) S < R
