The following sentence has been split into four segments. Identify the segment that contains a grammatical error.
When Serena / will arrive, / she will / call you.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. will arrive.
In this sentence, the correct form should be "arrives" because when the sentence refers to something that happens in the future after a condition is met (in this case, "when Serena"), we use the simple present tense after "when" for future events.
The corrected sentence is: "When Serena arrives, she will call you."
