Question

which word best completes the sentence? sahil plunged ______ into marine biology fieldwork this summer, quickly volunteering to survey oysters along the reefs at point pinole regional shoreline. consequently headlong hither foremost

Explanation:

To solve this, we analyze each option:

• "consequently" means as a result, which doesn't fit the context of "plunged...into" (needing a word about manner of plunging).
• "headlong" means with great speed or urgency, fitting "plunged headlong into" (showing eagerness in starting fieldwork).
• "hither" means to this place, which is irrelevant here.
• "foremost" means most prominent, not fitting the phrase structure.

Answer:

B. headlong
