223. Поиграйте в игру «Снежный ком». (§ 8, § 25) Whose glasses are these?

The question asks to identify the owner of the glasses. The phrase "Whose glasses are these?" is a direct question about possession. The preceding Russian text "Поиграйте в игру «Снежный ком»" translates to "Play the game 'Snowball'". This suggests the context is an exercise or game. The number "50" likely refers to a page number. Without further context or visual information about the glasses or their potential owners, a definitive answer cannot be provided based solely on the text. However, if this is a language exercise, the expected answer would be a possessive noun or pronoun. For example, "They are John's glasses." or "They are mine."
