The following passage is from an academic text about animal behavior. Which pronoun or noun correctly completes the sentence to establish proper subject-modifier agreement? Fill in the blank with the correct word or phrase.
Cevap:French biologist Karl von Frisch spent decades studying the communication patterns of honeybees. By translating their complex 'waggle dance' into spatial coordinates, 【he】 demonstrated that insects possess a sophisticated form of symbolic communication.
Cevap
The correct answer is the pronoun 'he' or the proper noun 'Karl von Frisch' (or 'the biologist' / 'the scientist').
The introductory modifying phrase 'By translating their complex "waggle dance" into spatial coordinates' describes an action that must be performed by a logical agent. The only logical agent in the context is the biologist Karl von Frisch. Therefore, the subject of the main clause must be a pronoun or noun referring to him (such as 'he', 'Karl von Frisch', or 'the biologist').
