1. The problem is to identify whether the given statements "2.", "3.", "4.", and "5." are truths (katotohanan) or opinions (opinyon). 2. In Filipino, "katotohanan" means a fact or truth that can be proven or verified. 3. "Opinyon" means a personal belief or judgment that is not necessarily based on fact or knowledge. 4. Since the user only provided numbers without context or statements, we cannot classify them as truths or opinions. 5. Therefore, the problem cannot be solved as stated because there is no content to analyze. Final answer: No classification possible without statements.
