A word has been given below and has been used in the sentences that follow. Identify the statements where the word has been used in a contextually and grammatically correct manner.

Advocate
(i) Community leaders continue to advocate for better public transport in the region.
(ii) The new infrastructure project was advocated out of substantial donations from external donors.
(iii) Civil society groups must advocate transparency in governance to strengthen democratic institutions.

The correct answer is Both (i) & (iii).

Let's understand the meaning and usage of the word 'Advocate':

As a verb, advocate means to publicly recommend, support, or argue for a particular cause, policy, or course of action.

Now, let's analyze each sentence:

(i) "Community leaders continue to advocate for better public transport in the region."
Here, 'advocate for' is used correctly to mean supporting or recommending better public transport services. Hence, sentence (i) is contextually and grammatically correct.

(ii) "The new infrastructure project was advocated out of substantial donations from external donors."
In this sentence, the word 'advocated' is used incorrectly. The sentence describes how the project was funded or financed using donations. A correct verb would be 'funded', 'financed', or 'built', not 'advocated'. Hence, sentence (ii) is contextually incorrect.

(iii) "Civil society groups must advocate transparency in governance to strengthen democratic institutions."
Here, 'advocate' is used correctly as a transitive verb meaning to promote or support transparency. Hence, sentence (iii) is contextually and grammatically correct.

Therefore, statements (i) and (iii) use the word 'advocate' correctly.
