Complete the sentence: Did you understand the speaker? No, he never spoke loudly ___ for me to hear.

• A. Enough
• B. Clearly
• C. Loudly
• D. Audibly

Answer: (A)

The main idea here is sufficiency: using enough to show that the action met the minimum level needed to produce the result. The natural way to say this is: “spoke loudly enough for me to hear.” Here, loudly describes how the speech happened, and enough signals that the volume reached the required threshold for being heard. That combination—adverb plus enough plus the purpose clause (“for me to hear”)—is a common, idiomatic way to express that something wasn’t sufficient. Other options don’t fit as smoothly. They would either change the nuance (for example, implying clarity or general audibility rather than just reaching the hearing threshold) or create awkward, repetitive phrasing if another adverb were used after the already stated “spoke loudly.”
