Zorluk: ZorShifts in Construction

Read the passage below. To maintain consistency in verb tense and sentence structure, fill in the blank with the correct form of the verb 'inspect'.

Cevap:In 1964, radio astronomers Arno Penzias and Robert Wilson set out to map signals from the Milky Way. Using a horn reflector antenna, they detected an unexplained, persistent buzz that they could not eliminate. To determine the source, the researchers first cleaned the antenna of nesting pigeons, and then they 【inspected】 the system's electrical connections to rule out mechanical interference.

Cevap

inspected
The correct verb form is 'inspected' because the passage is written in the simple past tense, describing historical events from 1964. The final sentence coordinates two actions in a sequence: 'first cleaned... and then they [blank]'. To maintain parallel structure and avoid an illogical shift in verb tense, the second action must also be expressed in the simple past tense.

Adım Adım Çözüm

1
Analyze the verbs in the surrounding context to determine the timeframe and mood of the passage.
The passage uses past-tense verbs ('set out', 'detected', 'could', 'cleaned') to describe historical events that occurred in 1964.
Establishing a consistent timeframe is necessary to avoid incorrect shifts in verb tense.
2
Identify the structure of the target sentence containing the blank.
The sentence uses a coordinate structure with a correlative time-sequence: 'first cleaned... and then they [blank]'.
Parallel structure requires that verbs in a coordinated sequence of actions share the same grammatical form and tense.
3
Determine the correct form of the verb 'inspect' to maintain parallel past-tense construction.
The past-tense form of 'inspect' is 'inspected'.
Using 'inspected' maintains grammatical consistency with the past-tense verb 'cleaned' and prevents an illogical shift in construction.

Anahtar Kavram

Shifts in construction occur when a writer unnecessarily changes grammatical patterns, verb tenses, or voices within a sentence or passage. Maintaining parallel structure and consistent verb tense is essential for clear writing.
