Improve the bracketed part of the sentence.
I wonder if the government (have resources to spare for) the poor refugees.
No improvement
The government is a third person singular noun. So, the corresponding verb must also reflect this. The correct verb, then, becomes 'has' and not 'have'.
To spare is to have something extra to give to someone. Here, the receiver is already given, viz, the refugees. So, the correct preposition would be resources 'for' them and not 'from' them.
Therefore, the correct answer is option 2.
Improved sentence - I wonder if the government$ has resources to spare for$ the poor refugees.$
