Answer:
In order to answer this question, we need to understand 2 things: which are the principal parts of a verb, and what is the stem of a verb.
Explanation:
Firstly, there are 4 principal parts in latin verbs:
1. the present, active, first person, singular (Example: amo – love)
2. the present active infinitive (Example: amare – to love)
3. the perfect, active, first person, singular (Example: amavi – have loved)
4. the past participle, singular (Example: amatus - loved)
Secondly, the stem of a verb is the one left once you take away the “–ar”, “-er”, or “–ir” ending.
Now, we can conclude that the first principal part gives you the present stem of the verb.
