1) To check the grammaticality of a sentence, it's necessary to analyze its structure, word choice, and punctuation.

Additionally, the word choice and punctuation are appropriate, so this sentence is grammatical.

2) Similarly, "Why might visitors not be welcome on Seeland?" is a grammatically correct sentence. It follows the subject-verb-object structure and uses appropriate word choice and punctuation.

3) "What are the citizens of the Aerican Empire like?" is also grammatically correct. The sentence consists of the subject "citizens," the linking verb "are," and the predicate adjective "like," properly forming a grammatical sentence.

4) "What happened to Danny when he accepted his friend’s invitation?" is a valid grammatical sentence. It follows the subject-verb-object structure and is punctuated correctly.

7) "What laws would you have if you were asked to rule a nation?" This sentence is grammatically correct. The tense is consistent, and it follows the subject-verb-object structure.

Regarding the paragraph, it consists of a series of statements rather than sentences. Each statement is in present tense and provides information about the situation. However, the sentences could be revised to add punctuation and proper sentence structure.
