ASAP PLEASE

You have been working through a lot of material that includes sorting grammatically correct and incorrect sentences.

Directions: Take a look at the sentences below and create a general rule in your own words that you think could explain what makes a sentence grammatically correct in Spanish when using verbs that require spelling changes in the preterite tense.
Hint: Note the subject pronoun.
Pay attention to the type of verb. (-ar, -er, -ir)
Determine the conjugations for regular preterite tense verbs.
See if any patterns occur.

Make your best guess and create your grammar rule for these 3 special types of verbs, then see if your rule applies to the example sentences. We are not looking for a textbook grammar rule, but rather a creation of your own.

ignore the girl on top the answer is "ser" and "estar", these two verbs differ on the condition of permanency of that what is being explained in the sentence.

It is better to use "ser" when you are expressing something that will be permanent, or most likely will be permanent.

it is better to use "estar" to express something that is likely to end in a short or medium term.

sometimes the verbs are interchangeable, in such cases is not needed to explain the length of the state expressed by the sentence.

The third sentence in the questions uses the literal translation from the English present continuous time to the Spanish "présente continuo"
