Select the most appropriate option to fill in blank number 5.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. for.
Context: The sentence talks about creating a healthier environment that would benefit future generations. The required word should show who the environment is meant to benefit, not direction or opposition.
Meaning of the words:
Towards: In the direction of something; implies movement or approach.
Of: Expresses possession or relation; not suitable to show benefit.
For: Indicates benefit, purpose, or intended recipient.
Against: Indicates resistance or opposition.
Correct word: For
Reason: Among the options, only “for” conveys the idea of benefit—the environment is created for the well-being of future generations. The other options are either unrelated to the context or grammatically incorrect.
Final Sentence: Research shows that communities adopting sustainable living not only reduce their carbon footprint but also create a healthier environment for future generations.
Hence the chosen option is correct.
