Step-by-step explanation:
We use the present subjunctive to express opinions, feelings, probabilities, desires, and uncertainties.
The verb in the first (piense) sentence is in the third person singular, and the conjugated verb is irregular.
In the second sentence(entiendas), the verb corresponds to the second person singular, and the verb is also irregular.
In the last sentence(sienta), the verb is conjugated in the third person singular, and the verb is also irregular.
