The option with the correct affirmative command to complete the sentence is:
c.<em></em><em><u>Duerme</u></em><em>.</em>
<em>Tonya, </em><em><u>duerme</u></em><em> ocho horas antes de manejar.</em>
Explanation:
In the sentence which translation is the next:
Tonya, <u>sleep</u> eight hours before driving.
is used the verb <em>"dormir"</em> in the <u>imperative conjugated form</u>, which would be depending on the personal pronoun:
<em>Tú: </em><u><em>Duerme</em></u><em>.
</em>
<em>Usted: </em><em>Duerma</em><em>.
</em>
<em>Él: </em><em>Duerma</em><em>.
</em>
<em>Ella: </em><em>Duerma</em><em>.
</em>
<em>Nosotros: </em><em>Durmamos</em><em>.
</em>
<em>Ellos: </em><em>Duerman</em><em>.
</em>
How the option said <u>"the correct affirmative tú command,"</u> the right option is "duerme." This sounds like <u>an order for Tonya</u>, who is the noun in the conjugation but is not conjugating the verb, you can see this because a comma separates this noun from the verb.
Yes, it’s great to get out there and observe natures features and all it has to offer. I love to observe different types of plants and animals I can find.
