Él querĂa un helado hace unas horas (He wanted an Ice Cream a few hours ago)

Él dijo que no podĂa hacer eso (He said he couldn´t do that)

Explanation:
The form in past of the verb conocer (to know) is conocĂ if we speak in first person.
The form in imperfect preterit of the verb querer (to want) is querĂa if we are speaking in third person. That is different from quiso which would be the correct form if we are forming a sentence in preterite.
The form of the verb saber (to know) in preterite is supo if we speak in third person.
The form in imperfect preterit of the verb poder (can) is podĂa if we are speaking in third person. That is different from pudo which would be the correct form if we are forming a sentence in preterite.
The form in imperfect preterit of the verb no querer (don´t want) is querĂa if we are speaking in first person. That is different from quise which would be the correct form if we are forming a sentence in preterite.
