Directions : Read the following passage carefully and answer the questions that follow .
For Q.1 - 5
Because goldfish can be kept easily in small ponds and aquariums, they make good pets, but like many other pets, they must have proper care and the right kind of place to live.
A two-inch fish requires a minimum of two gallons of water containing sufficient oxygen to support life.
Some oxygen will make its way into the water of an aquarium from the air that touches the surface. Plants in
an aquarium also help to furnish oxygen. Snails help to keep an aquarium clean. Thus, with plenty of plants
and snail, the water in an aquarium does not have to be changed frequently. A large lake may prove to be a
quite unsuitable abode for goldfish.
It is important that goldfish should not be overfed. They can be fed such things as dried insects in addition to
commercially-prepared goldfish food, but they should never be fed more than once a day. Even then, they
should not be given more food than can be consumed in about five minutes. This ensures prolonged life.
1. Which of the following statements is true ?
(A) Goldfish should be given food only once a day
(B) Snails eat up the goldfish in an aquarium
(C) Plants provide food to the snails
(D) Goldfish comes above the surface of water to get oxygen from air
2. Which of the following statements is not true ?
(A) Snails make the aquarium clean by eating up goldfish
(B) Two gallons of water with sufficient oxygen is enough for two-inch fish
(C) Goldfish can be made good pets
(D) Plants in an aquarium provide oxygen to goldfish
3. Which of the following helps supply goldfish with oxygen ?
(A) Snails (B) Plants (C) Dried insects (D) Aquarium
4. Water in an aquarium needs to be changed if
(A) there are plenty of snails and plants in it
(B) there is no sufficient oxygen in it(C) it is very clean and contains sufficient oxygen
(D) it does not contain goldfish food and dried insects
5. What is important to remember when feeding goldfish ?
(A) They should be fed more than once a day
(B) They should be fed at five-minute intervals
(C) They should be fed with plants and snails
(D) They should be fed only once a day
6. A million cinemas a year bring the same stale bladerdash.
