The past participle can be combined with the verb “ser” to express passive voice
Answer:
<u>Eres </u><u>Mexicano.</u>
Explanation:
Estas is a state of being somewhere/doing something
Example:
Are you playing soccer? = Estas jugando futbol?
Eres is a state of being something
Example:
Are you intelligent? = Eres intelligente?
The answer would be false, becasue it says "better" you would do your best or better work when you're not under pressure.
Hope this helps.
