Zorluk: OrtaShifts in Construction

Deep-sea oceanographers face extreme conditions when exploring hydrothermal vents. To study these underwater geysers, researchers rely on specialized submersibles and deployed high-tech sensors to map the ocean floor. This combination of tools allows scientists to collect chemical samples and record temperature readings at depths of several thousand meters.

Which choice most effectively maintains a consistent grammatical construction in the sentence?

  1. A
    rely on specialized submersibles and deployed high-tech sensors
  2. rely on specialized submersibles and deploy high-tech sensorsCevap
  3. C
    relied on specialized submersibles and deploy high-tech sensors
  4. D
    rely on specialized submersibles, but high-tech sensors were deployed by them

Cevap

The choice that uses 'rely on specialized submersibles and deploy high-tech sensors' maintains consistency in present tense and active voice.
The correct option maintains parallel structure and consistent present tense by using two active verbs ('rely' and 'deploy') to describe the actions of the researchers. This matches the present-tense narrative established in the rest of the passage.

Adım Adım Çözüm

1
Identify the tenses and voices of the verbs in the underlined portion of the sentence.
The verb 'rely' is in the present tense and active voice, while the verb 'deployed' is in the past tense.
Recognizing the forms of the verbs helps determine if there is an inconsistent shift in tense or voice between the compound predicates.
2
Analyze the surrounding context in the passage to establish the primary tense and voice.
The rest of the passage is written in the present tense ('face', 'allows') and uses the active voice to describe the scientists' actions.
Maintaining consistency with the established narrative tense and voice prevents unnecessary shifts in construction.
3
Evaluate the choices to find the one that uses consistent present-tense, active-voice verbs.
The choice using 'rely' and 'deploy' keeps both verbs in the present tense and active voice, ensuring a parallel and consistent construction.
Selecting this choice removes the grammatical shift, resulting in a cohesive and clear sentence.
