For many people, unintentionally hearing a mobile phone conversation causes more (1.annoy) _______ and frustration than the general background noise of people talking to each other.

This question requires a good knowledge of vocabulary as well as good comprehension skills. Let's use blank number 8 as an example on how to answer this question.

For number 8, the word in parentheses is "predict". However, the word should refer to the noun "conversation," which means it should be an adjective. We can make an adjective out of predict by adding -able, forming "predictable."

Still, "predictable" would be wrong. Right after blank number 8, the passage says we do not know where the conversation is going. That means we cannot predict it. Thus, we need to add un- and form "unpredictable" to complete number 8 properly.
