1. Which is the best version of the underlined portion of sentence 5: 'Compounding the problem is that food distribution system's currently require a lot of energy'?
Answer: C
Compounding the problem is that food distribution systems currently require a lot of energy.
The best version of the underlined portion is "systems" because the sentence refers to multiple distribution systems involved in food distribution, rather than a single system.
A) (as it is now)
This option is incorrect because the phrase "system's" implies possession, suggesting that something belongs to a single food distribution system. However, the context indicates that multiple systems are involved, making "systems" the appropriate term.
B) systems'
This option is incorrect as it uses a possessive form that suggests the distribution systems own something. The sentence does not require a possessive form, and using "systems'" does not accurately reflect the intended meaning of referring to multiple systems.
C) system's
This option is incorrect because it employs a possessive form, indicating ownership by a singular system. The context clearly indicates a reference to multiple systems, making "system's" inappropriate in this context.
D) systems
This is the correct option as it accurately captures the plural nature of the food distribution systems being discussed. The use of "systems" correctly aligns with the context of the sentence, referring to the collective energy requirement of all food distribution systems.
Conclusion
The correct answer is "systems," as it accurately reflects the plural nature of the food distribution networks discussed in the extract. All other options fail to convey the intended meaning, either by suggesting possession or by incorrectly limiting the reference to a single system. Thus, "systems" is essential for clarity and accuracy in the context of food distribution energy requirements.
