How should the phrase about exhibits be correctly constructed?

The phrase about exhibits is best constructed as "But also the solar system and plant exhibits" because it effectively conveys an inclusive and additive sense that aligns with the context of presenting additional information. The use of "also" indicates that what follows is supplementary to prior content, which is essential in linking ideas smoothly.

Using "solar system and plant exhibits" pairs the items correctly and maintains clarity for the reader. This structure emphasizes that both types of exhibits are important, allowing for a balanced and fluid connection within the sentence. It enhances the readability and coherence of the phrase by avoiding any potentially confusing conjunctions or punctuation issues present in the other options.

In contrast, alternatives like "the solar system or plant exhibits" suggest a choice between the two, which may not be appropriate if both exhibits are relevant. Similarly, "And the solar system and plant exhibits" lacks the appropriate transition that "also" provides, and “Exhibit, and solar system and plant exhibits” is grammatically awkward with misplaced commas and an unclear subject. Therefore, the correct construction clearly articulates the relationship between ideas in a precise and understandable manner.
