What action demonstrates fraudulent intent in the context of a mass lottery ticket?

Altering or forging a lottery ticket demonstrates fraudulent intent because it involves a deliberate act of deception aimed at obtaining a benefit, such as a monetary prize, through dishonest means. This action shows a clear intent to mislead the lottery organizers or other ticket holders about the authenticity or validity of the ticket.

In contrast, participating in a lottery without knowledge does not signify any intent to commit fraud, as the individual may be completely unaware of the ticket's value or status. Buying multiple tickets is a common practice in many lotteries and does not inherently suggest fraudulent behavior; participants often do this to increase their chances of winning. Furthermore, giving away free tickets, while it may raise questions about legality depending on the context, does not imply any fraudulent intent as it can be part of promotional activities or gifts with no intention to deceive.
