False.
Explanation:
1. The verb "saber" means "to know" in Spanish.
2. The preterite "yo" form of the verb "saber" is "supe," not "sube."
3. "Supe" is the correct past tense form for the first person singular "yo" (I) in the preterite tense of the verb "saber."
4. Therefore, the statement that the preterite "yo" form of the verb "saber" is "sube" is incorrect.
5. The accurate preterite "yo" form of the verb "saber" is "supe," which means "I knew" or "I found out" in English.
