Answer:

Part A: Recomendar (AR verb, stem - changing: e→ie)

Step 1: Identify the subject pronouns and conjugate

• Tú: For the second - person singular (tú), we take the stem of "recomendar" (recomend - ), change the stem vowel "e" to "ie", and add the AR - verb ending for tú (- as). So we get $\boldsymbol{\text{tú recomiendas}}$.
• Él/Ella/Ud.: For the third - person singular (él, ella, usted), we change the stem vowel "e" to "ie" in the stem "recomend - " and add the AR - verb ending for él/ella/usted (- a). So we get $\boldsymbol{\text{él/ella/ud. recomienda}}$.
• Nosotros/Nosotras: For the first - person plural (nosotros/nosotras), we use the regular AR - verb conjugation for the "nosotros" form. The stem remains "recomend - " (no stem - change for nosotros in stem - changing verbs) and we add the AR - verb ending for nosotros (- amos). So we get $\boldsymbol{\text{nosotros/nosotras recomendamos}}$.
• Vosotros/Vosotras: For the second - person plural (vosotros/vosotras), we change the stem vowel "e" to "ie" in the stem "recomend - " and add the AR - verb ending for vosotros (- áis). So we get $\boldsymbol{\text{vosotros/vosotras recomendáis}}$.
• Ellos/Ellas/Uds.: For the third - person plural (ellos, ellas, ustedes), we change the stem vowel "e" to "ie" in the stem "recomend - " and add the AR - verb ending for ellos/ellas/ustedes (- an). So we get $\boldsymbol{\text{ellos/ellas/uds. recomiendan}}$.

Part B: Pedir (IR verb, stem - changing: e→i)

Step 1: Identify the subject pronouns and conjugate

• Yo: For the first - person singular (yo), we take the stem of "pedir" (ped - ), change the stem vowel "e" to "i", and add the IR - verb ending for yo (- o). So we get $\boldsymbol{\text{yo pido}}$.
• Tú: For the second - person singular (tú), we change the stem vowel "e" to "i" in the stem "ped - " and add the IR - verb ending for tú (- es). So we get $\boldsymbol{\text{tú pides}}$.
• Él/Ella/Ud.: For the third - person singular (él, ella, usted), we change the stem vowel "e" to "i" in the stem "ped - " and add the IR - verb ending for él/ella/usted (- e). So we get $\boldsymbol{\text{él/ella/ud. pide}}$.
• Vosotros/Vosotras: For the second - person plural (vosotros/vosotras), we change the stem vowel "e" to "i" in the stem "ped - " and add the IR - verb ending for vosotros (- ís). So we get $\boldsymbol{\text{vosotros/vosotras pedís}}$.
• Ellos/Ellas/Uds.: For the third - person plural (ellos, ellas, ustedes), we change the stem vowel "e" to "i" in the stem "ped - " and add the IR - verb ending for ellos/ellas/ustedes (- en). So we get $\boldsymbol{\text{ellos/ellas/uds. piden}}$.

Part C: Querer (ER verb, stem - changing: e→ie)

Step 1: Identify the subject pronouns and conjugate

• Yo: For the first - person singular (yo), we take the stem of "querer" (quer - ), change the stem vowel "e" to "ie", and add the ER - verb ending for yo (- o). So we get $\boldsymbol{\text{yo quiero}}$.
• Él/Ella/Ud.: For the third - person singular (él, ella, usted), we change the stem vowel "e" to "ie" in the stem "quer - " and add the ER - verb ending for él/ella/usted (- e). So we get $\boldsymbol{\text{él/ella/ud. quiere}}$.
• Nosotros/Nosotras: For the first - person plural (nosotros/nosotras), we use the regular ER - verb conjugation for the "nosotros" form. The stem remains "quer - " (no stem - change for nosotros in stem - changing verbs) and we add the ER - verb ending for nosotros (- emos). So we get $\boldsymbol{\text{nosotros/nosotras queremos}}$.
• Vosotros/Vosotras: For the second - person plural (vosotros/vosotras), we change the stem vowel "e" to "ie" in the stem "quer - " and add the ER - verb ending for vosotros (- éis). So we get $\boldsymbol{\text{vosotros/vosotras queréis}}$.
• Ellos/Ellas/Uds.: For the third - person plural (ellos, ellas, ustedes), we change the stem vowel "e" to "ie" in the stem "quer - " and add the ER - verb ending for ellos/ellas/ustedes (- en). So we get $\boldsymbol{\text{ellos/ellas/uds. quieren}}$.
