Aryavarta Gramin Bank Clerk Exam, 2011 : General English Solved Paper

Aryavarta Gramin Bank Clerk Exam, 2011
(Held on 20-11-2011)
General English : Solved Paper

Directions—(Q. 1–10) Read the following passage carefully and answer the questions given below it. Certain words have been printed in bold to help you locate them while answering some of the questions.

Once upon a time, there was a stork that lived by catching fish from a particular tank. As the years went by, the stork grew older and weaker and its ability to catch fish diminished. At times it would even starve. The stork knew that it had to do something to survive.

One day it stood by the side of the tank with a very forlorn look on its face. The frogs, fish and crabs wondered why it was not trying to catch any food. A big crab asked the stork what the matter was. The stork answered that it was sad because all the fish in the tank were going to die and so it would have to starve. The stork said that it had heard that people were going to fill the tank with mud and grow crops over it. The fish were very worried and asked the stork to help them.

The stork offered to take all of them to a bigger tank some distance away. But it said that it needed to rest between trips because of old age. It would only be able to carry a few fish at a time.

On its first trip, the stork took a beakful of fish. It flew to a big rock and had a good meal. Thereafter, it rested for a while, and when it was hungry again, the stork took a second trip. In this manner, the stork took a trip each time it was hungry.

The big crab in the tank also wanted to save itself and it requested the stork to take it too. The stork thought it was a good idea to try a new dish. It agreed to take the crab on its next trip.

After the stork flew up with the crab, the crab looked down to see what the new surroundings would be like. All it could see was dry land. When the crab questioned the stork about this, the stork laughed wickedly and pointed to the rock below where the crab saw a heap of fish bones. The crab realized that it was to be the stork’s next meal. So the crab dug its claws into the stork’s neck and would not let go till the stork fell to the ground and died. The crab then cut off the stork’s head and returned home to show it to all the other fish and share the story of its adventure with the stork.

Directions—(Q. 1–3) Choose the word which is most similar in meaning to the word printed in bold as used in the passage.
