I have a PC, not Mac. And I tried to answer them in the best of my ability. The thing that really threw me are the reflexives.

Enciendamela ahora
= No me la Encienda

Inscribete en ese curso
= (still unsure)

Quitatelos antes de comer
= No los Quitates

Repitesela al chofer
= No la repites

Llevalo al cine esta tarde
= No lo Llevale

Desela al nino
= No la Dese

One more thing. I need the verb Cortarse and Llegar in preterite tense:

Is this correct:
Llege
Llegiste
Llego
Llegimos
Llegieron

Im pretty sure this one is correct as well. I probably missed the o-ue part in this one.
me Corte
te Cortiste
se Corto
nos Cortimos
se Cortieron
(note: I my doesn't let us use vosotros)

Great job on your attempts to answer the questions! Let's go through each sentence and provide the correct reflexive pronoun and verb form.

1. Enciendamela ahora.
The reflexive pronoun here is "me" (for the indirect object pronoun "me"). To form the negative command, you need to add "no" before the pronoun and attach the pronoun to the end of the verb. So the correct answer is: "No me la enciendas."

2. Inscribete en ese curso.
The reflexive pronoun here is "te" (for the subject pronoun "tú"). The question asks for the negative command, so the correct answer is: "No te inscribas en ese curso."

3. Quitatelos antes de comer.
The reflexive pronoun here is "te" (for the subject pronoun "tú"). The question asks for the negative command, so the correct answer is: "No te los quites antes de comer."

4. Repitesela al chofer.
The reflexive pronoun here is "te" (for the subject pronoun "tú"). To form the positive command, you need to attach the pronoun to the end of the verb. So the correct answer is: "Repítela al chofer."

5. Llevalo al cine esta tarde.
The reflexive pronoun here is "lo" (for the direct object "it" referring to a masculine noun). To form the negative command, you need to add "no" before the pronoun and attach the pronoun to the end of the verb. So the correct answer is: "No lo lleves al cine esta tarde."

6. Desela al nino.
The reflexive pronoun here is "la" (for the direct object "it" referring to a feminine noun). To form the negative command, you need to add "no" before the pronoun and attach the pronoun to the end of the verb. So the correct answer is: "No se la des al niño."

Moving on to the verb forms in the preterite tense:

"Llegar" in the preterite tense:
- Yo: Llegué
- Tú: Llegaste
- Él/Ella/Usted: Llegó
- Nosotros/Nosotras: Llegamos
- Ellos/Ellas/Ustedes: Llegaron

"Cortarse" in the preterite tense:
- Yo: Me corté
- Tú: Te cortaste
- Él/Ella/Usted: Se cortó
- Nosotros/Nosotras: Nos cortamos
- Ellos/Ellas/Ustedes: Se cortaron

Remember, the "o-ue" stem change applies to verbs in the present tense, not in the preterite tense.

Great work on your efforts, and keep practicing!
