Question

Difficulty: MediumModifier Placement

Read the passage below. To ensure that the introductory phrase logically modifies the subject of the sentence, which researcher's name should be placed in the blank?

Answer:Having spent decades studying chimpanzee behavior in Gombe Stream National Park, 【Jane Goodall】 revolutionized our understanding of primate social structures.

Answer

Jane Goodall
The introductory modifier describes someone who spent decades studying chimpanzees in Gombe. To avoid a dangling modifier, the subject immediately following the comma must be the entity performing that action. Jane Goodall is the correct subject because she is the one who conducted the research.

Step-by-Step Solution

1
Analyze the introductory modifier to identify the action described.
The opening modifier is 'Having spent decades studying chimpanzee behavior in Gombe Stream National Park', describing the action of studying chimpanzees.
An introductory participial phrase must describe the subject immediately following the comma.
2
Determine the logical subject who performed the action.
The person who performed this long-term study is Jane Goodall.
If any other noun (such as an abstract concept or a scientific discovery) is placed in the blank, the modifier will dangle and lead to an ungrammatical construction.
