17. Apart from being a basic requirement for plant life, the propagation of some plant species is also helped by rain.
Answer: C
Rain also helps in the propagation of some plant species.
This version is clear and concise, effectively conveying that rain plays a supportive role in the propagation of certain plant species.
A) the propagation of some plant species is also helped by rain
While this option is grammatically correct, it is less direct and slightly more wordy than necessary. It does not convey the same level of clarity as the correct answer.
B) some plant species are also helped by rain to propagate them
This option is awkwardly structured and introduces unnecessary complexity. The phrase "to propagate them" can lead to confusion, detracting from the intended message about rain's role.
C) rain also helps in the propagation of some plant species
This option is the most effective as it succinctly states that rain is beneficial for the propagation of certain plants. The structure is straightforward and maintains clarity, making it the best choice.
D) it is also helpful for the propagation of some plant species to have rain
This option is overly complicated and passive. The phrasing makes it less engaging and can obscure the direct relationship between rain and plant propagation, making it less effective than the correct answer.
Conclusion
Option C is the most effective choice, clearly stating the relationship between rain and the propagation of plant species without unnecessary complexity. The other options either lack clarity, introduce awkward phrasing, or are overly verbose, making them less suitable for conveying the intended meaning.
