Question

Fill in the blank using the most appropriate option to form a compound noun.
Press the ____ alarm. I see some sparks in the circuit.
a- morning
b- burning
c- fire
d- dark

Answer 1

Hint: Nouns are words that indicate the name of a person, place, thing, or animal. For example- dog, girl, park, etc. Compound nouns are those nouns that are made up of two or more words. For example- toothpaste, playground, dogfood, etc.

Complete answer:
As given in the hint, compound nouns consist of a noun that is modified by another noun or adjective.
For example- Sunflower. Here, both the sun and flowers are nouns.
In the given question: We can conclude that X asked Y to press the fire alarm because he saw some sparks in the circuit. Here, ‘fire alarm’ is an open compound noun that consists of a space between the two nouns.
Now, let’s examine the given options-
Option a- ‘morning’ is an incorrect option because one does not press the morning alarm in case of a fire or short-circuit.
Option b- ‘burning’ is an incorrect option because there is no such thing as a burning alarm.
Option c- ‘fire’ is the correct option because ‘fire alarm’ is a compound noun that is useful during a fire or short-circuit.
Option d- ‘dark’ is an incorrect option because there is no such thing as a dark alarm. The correct answer is Option ‘c’.

Note:
 Keep in mind, compound nouns can also consist of hyphenated words that are joined with the help of a hyphen. For example- mother-in-law, six-pack, etc.
