Deleting the underlined text in sentence 14 is essential to maintain consistency with the claim in sentence 15, ensuring clarity and coherence in the argument about the potential dangers posed by goats in the context of human safety concerns. Here option E is correct.
This is because it contradicts the writer's claim in sentence 15 that goats behave differently after they are accustomed to human contact.
The statement, "some thoughtless and irresponsible people feed the goats directly," implies that goats are always attracted to humans, regardless of their behavior after getting accustomed to human contact.
Deleting this text aligns with maintaining consistency in the writer's argument and reinforces the idea that the goats' behavior can change with regular human interaction, as mentioned in sentence 15. This approach ensures clarity and coherence in the overall message about the potential dangers posed by goats in the context of human safety concerns. Here option E is correct.
