1. i go to the market ride a car/by a car
2. mother pushes/prompts a cow

Explanation:

use simple present tense.

(+) S + V1 + O/complement?

(-) S + do/does + V1 + O/complement?

(?) do/does + S + V1 + O/complement?

• add s/es in the last V1, and the Aux is does, when the subject is singular person, like he/she/it

simple PRESENT TENSE, is used when the activity is the general thruth, and was become a habit.

• pushes that general used in the American and British people, but for "prompts" just used, in the American people/for US, not general in UK.
