Question

Difficulty: MediumShifts in Construction

Fill in the blank with the correct form of the verb *analyze* to maintain a consistent grammatical construction and avoid an inappropriate shift in verb tense.

Answer:While conducting research on urban heat islands, the meteorologist recorded temperature changes across the city, mapped the density of concrete structures, and 【analyzed】 data from satellite imagery.

Answer

analyzed (or analysed)
The correct answer is 'analyzed' (or 'analysed') because it is the simple past tense form of the verb, which matches the simple past tense verbs 'recorded' and 'mapped' in the list. This maintains parallel structure and avoids an inappropriate shift in verb tense.

Step-by-Step Solution

1
Identify the structure and main verbs of the sentence.
The sentence describes a list of three actions completed by the meteorologist: 'recorded temperature changes', 'mapped the density', and the blank action regarding 'data from satellite imagery'.
Understanding the sentence structure helps identify if there is a parallel list requiring consistent verb tense and form.
2
Analyze the tense of the existing verbs in the parallel construction.
The verbs 'recorded' and 'mapped' are both in the simple past tense.
To maintain parallel structure and avoid an inappropriate shift in construction, the third verb in the series must match the simple past tense form.
3
Conjugate the verb *analyze* to match the simple past tense.
The simple past tense of *analyze* is *analyzed* (or *analysed* in British English).
Using the past tense form completes the parallel structure consistently.
