Explanation:

Question 4:

• For "Los paisajes son maravillosos":
• Grammatical gender: "paisaje" (singular) is masculine, and the plural "paisajes" retains the grammatical gender (masculine). So "masculine (based on the grammatical gender of the noun)" applies.
• Number: "paisajes" is plural, so "plural (based on the number of who/what is being described)" applies.
• Biological gender: "paisaje" (landscape) has no biological gender, so the biological gender options are incorrect.
• Singular is incorrect as "paisajes" is plural.

• For "Los animales son exóticos":
• Grammatical gender: "animal" (singular) is masculine, and the plural "animales" retains the grammatical gender (masculine). So "masculine (based on the grammatical gender of the noun)" applies.
• Number: "animales" is plural, so "plural (based on the number of who/what is being described)" applies.
• Biological gender: While "animal" can have biological gender, the adjective "exóticos" here is based on the grammatical gender of the noun "animales" (which is masculine in grammar, even if animals can be male/female). So the grammatical gender option is more relevant here, and biological gender options are less accurate for the adjective agreement.
• Singular is incorrect as "animales" is plural.

• For "Los argentinos son generosos y relajados":
• Grammatical gender: "argentino" (singular) is masculine, and the plural "argentinos" retains the grammatical gender (masculine). So "masculine (based on the grammatical gender of the noun)" applies.
• Number: "argentinos" is plural, so "plural (based on the number of who/what is being described)" applies.
• Biological gender: "argentinos" (Argentines) can refer to males (biological gender), but the adjective agreement here is based on the grammatical gender of the noun "argentinos" (masculine in grammar, used for a group that may include both genders, but grammatically masculine plural). So the grammatical gender option is key, and biological gender is less precise for the adjective agreement.
• Singular is incorrect as "argentinos" is plural.

Answer:

• masculine (based on the grammatical gender of the noun)
• plural (based on the number of who/what is being described)
