Which of the following is NOT a correctly written adverb?
Answer b. tranquilomente.
Explanation : In Spanish some adverbs are built by adding the suffix "mente" to an adjective, but in this case the adverb is irregular and changes the ending of the adjective before adding the suffix. "Tranquilo" changes to "tranquila"
The correct adverb should be "tranquilamente".
