The correct answer is that option 3 is incorrect because:
This approach could lead to information overload, making it difficult for Jabu to draw meaningful conclusions applicable to his initial interest.
By expanding his search to include all types of urban spaces globally, Jabu may encounter an overwhelming amount of information that does not specifically pertain to the unique context of urban green spaces in Cape Town. This could dilute his focus and hinder his ability to arrive at targeted, relevant insights regarding the impact of urban green spaces on mental health in his specific study area. Therefore, refining his research question to align closely with his objectives, as suggested in option 2, is a more effective approach.
