Explanation:

For each sentence, when there is a quantifier like "three", "many", "some" etc. before a noun, the noun should be in plural form if applicable. Regular nouns usually form their plural by adding -s or -es.

1. The noun "border" should be plural "borders" as Europe, Asia, and North America have multiple northern borders.
2. "island" should be "islands" since "many" indicates multiple islands.
3. There is no error as "city" is singular and the sentence context allows it.
4. "community" should be "communities" because of "many".
5. "month" should be "months" as "are" indicates plural.
6. "patch" should be "patches" to agree with the plural verb "cover".
7. "grass" is usually uncountable, but if referring to different types, it can be "grasses".
8. "moss" is usually uncountable, but if different kinds are meant, "mosses" can be used.
9. "bush" should be "bushes" as "are" indicates plural.
10. "valley" should be "valleys" as "are" indicates plural.
11. "berry" should be "berries" as "even" implies multiple berries ripening.
12. "mine" should be "mines" as "produce" indicates multiple mines.
13. "company" should be "companies" as "pump" indicates multiple companies.
14. "explorer" should be "explorers" as "attracts" implies multiple explorers.
