10. The best placement for sentence 12 within the third paragraph would be

Answer: C

Explanation:

Sentence 12 should be placed after sentence 13 to maintain logical flow.

Repositioning sentence 12 after sentence 13 ensures a coherent progression of ideas regarding meal planning and its impact on food waste reduction. This placement effectively links the concept of improved meal planning to the outcomes discussed in sentence 13.

A) where it is now

Keeping sentence 12 in its current position disrupts the logical flow of ideas presented in the paragraph. Its original placement does not effectively connect meal planning to the subsequent discussion on shopping habits and energy conservation.

B) before sentence 11

Placing sentence 12 before sentence 11 would lead to confusion, as it would disrupt the sequence of suggestions on informing shoppers about shelf life. It would not create a clear connection to the preceding idea of informing shoppers about true shelf life.

C) after sentence 13

This placement is the most effective as it directly connects the idea of better meal planning, discussed in sentence 12, to the potential benefits outlined in sentence 13. It allows for a seamless transition from discussing meal efficiency to the implications for shopping habits and waste reduction.

D) after sentence 14

Positioning sentence 12 after sentence 14 would further complicate the paragraph, as it would disconnect the idea of meal planning from the previously discussed benefits. This would hinder the reader’s understanding of the relationship between planning meals efficiently and reducing spoiled food.

Conclusion

Sentence 12 is best placed after sentence 13 because it logically follows the discussion on meal planning's benefits. The correct answer enhances the coherence of the paragraph by ensuring that the ideas about meal efficiency, shopping behavior, and waste reduction are clearly connected, while all other options disrupt this flow.
