Task: Question Answering
Input (English): Passage: Half-witted longtime friends Albert, Isaac, Mozart "Mo" (DJ Durano), Michaelangelo "Mike" (Martin Escudero) and  Aristotle "Aris" (Marvin Agustin) were used to living moronic yet pretty normal and hassle-free lives until successful careerwoman Beckie Pamintuan accused them of killing her father and ruin everything for them. The Moron 5 are more than sure of their innocence but for the life of them, they can't find any single satisfactory argument on how to prove it especially when their opponent would do everything to punish them for whim. Spending three miserable years in prison trying different failed comedic attempts to get out, they finally figured a way to escape. They stalked Beckie and tried to understand why she's fighting so hard to have them imprisoned when it's clear as day that what happened three years ago was a nonsense frame-up. An opportunity came when Beckie's driver got fired for having an affair with her maid and Albert volunteered to apply to replace him. He infiltrated the Pamintuan Residence and together with his four crazily daft friends, they've gathered information about the curious family yet to them, it isn't making any sense at all especially Vecky's unexplained hatred to the five of them. Why is Beckie fighting so hard to have them suffer? The Moron 5 will try harder to know and hopefully understand what's really going on although little did they know that by doing so, everything that they hold dear might be at risk. 
Question: What are the first names of the four crazily daft friends that helped Albert gather information about the Pamintuan family?
Output (English): Isaac.
