Which sentence is most clearly written?

The choice that is most clearly written provides a straightforward structure that enhances comprehension. In this sentence, the subject ("the inner workings of the engine") is clearly stated at the beginning, followed by the predicate ("made much more sense to Linda") and the modifying clause ("after she read the manual again"). This clear progression allows readers to easily follow the logic of the sentence, understanding that Linda's improved understanding of the engine's workings is directly tied to her rereading of the manual.

The other options present different logical and grammatical issues that can lead to confusion. For example, the first option starts with an introductory phrase that could mislead readers about who is performing the action, making it harder to grasp the subject's relationship to the action. In contrast, the clearer structure in the second choice immediately establishes the main idea before providing additional information.
