Answer: These are some possible answers, conjugating the verbs in the present tense:
1. Investigo
2. Hace
3. Buscan
4. Leemos
5. Aprende
6. Practicas
Explanation: Just to elaborate a little on the answer, it can also be added that in this exercise we are conjugating the verbs (in brackets) in the Present Tense, which is frequently used in Spanish and is primarily used to describe a present and/or regular event, as well as to describe general truths. According to the verb ending (-ar, -er, or -ir), the present tense adopts various endings.
So, for instance, if the verb ends in -ar, like BUSCAR, the present tense is formed by keeping the root of the word and adding the following endings for each person: -o, -as, -a, -amos, -áis, -an.
If the verb ends in -er, like HACER, you need to add the following endings: -o, -es, -e, -emos, -éis, -en.
Finally, if the verb ends in -ir, you need to add the following endings: -o, -es, -e, -imos, -ís, -en.
