The area of land where water is drained downhill into a body of water is known as a drainage basin

true, i don't really know what you're asking but from the info you provided im guessing the answer is true.

the answer is admiramos

the rule for verbs is whoever you are referring to (in this case 'nosotros'), you need to change the ending of the word.

nosotros - amos

yo - o

tu - as

el, ella, usted - a

ellos, ellas, ustedes - an

(examples: nosotros bailamos (instead of bailar) or yo hablo (instead of habla)
