What can we deduce about Sam packing his toys for the sleepover?

Choosing the response that states Sam was excited about the sleepover is supported by the idea that packing his toys suggests anticipation and enthusiasm for spending the night away from home. When someone engages in activities such as packing, it often reflects a positive attitude towards the upcoming event. Sam's decision to include his toys indicates he wants to make the sleepover more enjoyable, which aligns with the notion of excitement.

The other options do not support this inference; they either suggest negative feelings toward toys or preferences that are not substantiated by the provided context. Therefore, it can be concluded that the act of packing toys is a strong indicator of Sam's excitement for the sleepover.
