Identify the sentence that correctly maintains consistency in verb tense:
Answer and explanation
Correct answer: C. When the valve opened, the coolant rushed into the chamber and equalized the internal pressure.
- Step 1: Unwarranted shifts in verb tense confuse the chronological sequence of events.
- Step 2: Here, the past time frame is established by 'opened'. Consistency requires all sequential past actions to remain in the simple past tense: 'opened... rushed... equalized'.
- Step 3: Option 1 maintains complete past tense consistency.
Answer
When the valve opened, the coolant rushed into the chamber and equalized the internal pressure.
Why not the others: The other sentences abruptly switch between past tense, present tense ('rushes', 'opens'), and future modals ('will equalize') without logical justification.
