Error: allowed
Correction: allow
Explanation: The sentence "Embrace change as an opportunity for personal growth and allowed it to improve your life" has a verb form error. The sentence begins with the imperative verb "Embrace," so the second verb, joined by "and," should also be in its base form for parallelism and consistency.
"Allowed" is past tense, disrupting this parallel structure. Replacing "allowed" with "allow" makes both verbs imperative, creating a clear instruction.
This correction improves the sentence's flow, clarity, impact, and grammatical correctness.
Therefore, the corrected sentence is: "Embrace change as an opportunity for personal growth and allow it to improve your life."
