To "mantener la salud," which means "to maintain health" in Spanish, one might:

2. Hacer ejercicio regularmente - True (Exercise regularly)
3. Dormir lo suficiente - True (Get enough sleep)
4. Evitar el consumo excesivo de alcohol y tabaco - True (Avoid excessive consumption of alcohol and tobacco)

These are basic health principles that would contribute to maintaining good health. If you have specific options you'd like evaluated as true or false, please provide them, and I can assist you further.

To answer this question, we need to understand the rules for pluralizing nouns in Spanish. In Spanish, most nouns form their plurals by adding "-s" to the end. However, there are some exceptions, and one of them involves the letter "z."

In general, when a noun ends in "-z," it changes to "-ces" in the plural form. So, if we have a noun like "la nariz" (the nose), its plural form would be "las narices" (the noses). As you can see, the letter "z" changes to "ces" in the plural form.

Therefore, the correct answer to the question is: The letter "z" changes to "ces" at the end of a plural noun.
