The task is to connect each sentence with the correct explanation of why punctuation marks are placed (or not placed) in a certain way. Since no punctuation is provided in the sentences, we need to infer the correct punctuation based on grammatical structure and meaning.
Исчезают последние клочки снега и на свет выходит зелёная листва.
Explanation Logic: This is a compound sentence joined by the conjunction "и" (and). The two parts of the sentence ("Исчезают последние клочки снега" and "на свет выходит зелёная листва") are independent clauses. Therefore, a comma is needed before the conjunction "и" to separate them.
Кружатся листья по полянам а гуси длинным караваном над лесом держат перелёт.
Explanation Logic: This is also a compound sentence joined by the conjunction "а" (but/and). The two parts of the sentence ("Кружатся листья по полянам" and "гуси длинным караваном над лесом держат перелёт") are independent clauses. Therefore, a comma is needed before the conjunction "а" to separate them.
Note: The task implies matching sentences to explanations of punctuation, but the explanations themselves are not provided in the image. This response provides a logical explanation for how punctuation *would* be applied to these sentences if they were presented with options for matching.
