Choose the word which has the same meaning as of the italicized words in the two sentences-
1) The distance from Amman to Bombay is too far to be covered by the A 320 planes.
2) Ashish waited at the door for his father with a sad face.
a) Bad
b) Heavy
c) Long
d) Unlucky

Hint: Words that can be used at the place of one another are synonymous in nature. They have the same meaning but different pronunciations.

Complete answer:
 The two sentences have a different meaning and two different italicized words. The italicized word of the first sentence is 'far' and for the second sentence, it is 'sad'. We have to find a word which can replace both of them. 'Far' means 'at a great distance', whereas 'sad' means 'in a low mood'.
Now, let us examine all the given options to find out the correct answer :
Option 'a' is Bad. It is an adjective that means poor quality and low standards. For example, Her clothes are bad.
Option 'b' is Heavy. It is an adjective that means of great weight. For example, The truck was heavy, not light.
Option 'c' is Long. It is an adjective which means measuring the great distance from end to end. For example, The path is way too long. This expression can be used in both the given sentences as we often use 'long face' as an expression of pointing out sadness. It is an idiom.
Option 'd' is Unlucky. It is an adjective that means having or resulting from bad luck. For example, I am unlucky for the trip.
As we have analyzed all the given options, we can easily figure out the correct answer. Here, the word which can be used in the place of the given words is - long. Hence, option 'c' is the correct option.

Note:
Many words also result in creating idioms. Idioms don't always have a literal meaning, they may also have metaphoric meanings. One must have a geek knowledge of general idioms.
