Questions: Suppose you are writing about the different components of a solar-power system as part of an essay that argues for solar power as an alternative energy source. Which expert writing move would help you achieve your purpose? - the division-into-parallel parts move - the for example move - the summary/however move - the comparison/contrast move

The answer is the first one: the division-into-parallel parts move.

Explanation for each option:

1. The division-into-parallel parts move: This move is effective when writing about the different components of a solar-power system. It allows you to break down the system into its individual parts, making it easier for the reader to understand each component's role and how they work together. This approach is particularly useful in technical or complex subjects, such as solar power systems, where clarity and organization are crucial.

2. The for example move: While providing examples can be helpful in illustrating points, it may not be the most effective strategy for organizing and explaining the different components of a solar-power system. This move is more suited for supporting specific claims or arguments rather than structuring an entire section of an essay.

3. The summary/however move: This move is typically used to summarize information and then introduce a contrasting point or exception. It is not the best choice for detailing the components of a solar-power system, as it does not inherently provide a structure for explaining multiple parts.

4. The comparison/contrast move: This move is useful for highlighting differences and similarities between two or more items. While it can be beneficial in certain contexts, it is not the most appropriate choice for explaining the components of a solar-power system, unless you are specifically comparing different types of systems or components.

In summary, the division-into-parallel parts move is the most suitable expert writing move for explaining the different components of a solar-power system in an essay advocating for solar power as an alternative energy source.
