Final answer:
The best word to complete the sentence about a vocabulary quiz prediction given by Mr. Walsh is 'anticipated.' The correct answer is option (b).
Step-by-step explanation:
The question from Mr. Walsh's student is about choosing the correct word to complete the sentence about a specific prediction. Given the context of a short vocabulary quiz, the most suitable word from the options given would be 'anticipated' which means to expect or predict something. The sentence then reads, 'Mr. Walsh gave a short vocabulary quiz today, as you had anticipated.'
Choices 'projected' and 'speculated' could also fit in a broader context, but they are not as precise. 'Projected' often relates to a more formal estimation or forecast, commonly used in business or scientific contexts. 'Speculated' implies a level of uncertainty or guessing, which does not seem appropriate here. 'Prophesied' is not suitable because it is more commonly used for grand or divine predictions, not everyday events like a quiz.
In terms of vocabulary application, it is vital that students learn to choose words that match the context of the sentence accurately. Understanding the nuances between synonyms is crucial for effective communication. In this case, anticipated clearly communicates that the event was expected based on an inferred or known pattern, which is a typical scenario for classroom quizzes.
