BigorU [14]

Answer and Explanation:

<u>A complex sentence is formed by joining an independent clause and a dependent one. However, we have four different sentences here. We must join them and use a subordinating conjunction to form a complex sentence.</u>

- Since choosing between a desktop and a laptop models is a decision for the consumer, the decision is personal.

- Provided that choosing between a desktop and a laptop models is a decision for the consumer, the decision is personal.

Answer:The underlined phrase has a figurative  meaning, which creates an inspired voice.

When something is said to be figurative, it means that metaphorical terms are being used to describe it such that it is easier to understand. The description is therefore not literal. In calling the gymnasts "supergirls", the speaker does not mean that they have super powers but that they are doing great things like a super hero would.

This is said in an inspired voice because the speaker wishes to be like them someday.
