Choose whether the following is true or false:
The abstract noun form of “obey” is obedience.
a)True
b)False

Hint: To be able to answer the question, the meaning of abstract nouns must be known.

Complete step-by-step answer:
An abstract noun indicates a quality, an idea, or state, rather than a tangible entity. For example, the abstract noun of wise is wisdom. That of proud is pride. Other examples are pride, joy, anger, liberty, freedom, etc.
Obey is a verb which means to carry out, perform, or execute a given command or instruction. Verbs can also have abstract noun forms, like the abstract noun form of conserve is conservation. The abstract noun form of imagine is imagination. The abstract noun form of inform is information. The abstract noun form of collect is collection. The abstract noun form of execute is execution. So, we can see that abstract nouns are not only for nouns and pronouns. The abstract noun of “obey” is obedience.
 Option a “true” is the correct option, as we have established that the given abstract noun is the one for the given verb. Option b, “false” is the incorrect choice.

Note: The most important part is that one must know the meaning of abstract nouns and if the given verb and the abstract noun correspond to each other.
