Answer:
(Although I wrote in time), I did not receive a ticket
Step-by-step explanation:
An adverb clause is a group of related words that have at least a subject and a verb, and whose function is to modify or add detail to adjectives, verbs or other adverbs. This type of clause often answers questions such as "Why?", "How?", "When?", "Where?" and "under what circumstances something takes place?" and begin with a coordinating conjunction like "Although."
In the sentence, "Although I wrote in time" is the adverb clause because it has a subject: I and a verb: wrote and it modifies the verb "receive" and answer to the following question: In what circumstances or conditions I did not receive a ticket?
