Answer 3

To solve this problem, we can create a table to track which decorations each student made. Let's analyze the given information and fill in the table accordingly:

| Students | Snowflakes | Crackers | Gilded Nuts | Chains | |----------|------------|----------|-------------|--------| | Yulia | | | | | | Nadya | | | | | | Seva | | | | | | Lenya | | | | |

From the given information: - Yulia and Lenya did not gild nuts. - Seva and Lenya did not cut out snowflakes. - Yulia did not make snowflakes or crackers.

Based on this information, we can fill in the table as follows:

| Students | Snowflakes | Crackers | Gilded Nuts | Chains | |----------|------------|----------|-------------|--------| | Yulia | | | | | | Nadya | | | | | | Seva | | | | | | Lenya | | | | |

- Yulia did not make snowflakes or crackers, so she must have made chains. - Nadya's decoration is not specified, so we cannot determine what she made. - Seva did not cut out snowflakes, so he must have made gilded nuts. - Lenya did not gild nuts, so he must have made snowflakes.

Therefore, based on the given information, we can conclude that: - Yulia made chains. - Nadya's decoration is unknown. - Seva made gilded nuts. - Lenya made snowflakes.

The table below summarizes the decorations made by each student:

| Students | Snowflakes | Crackers | Gilded Nuts | Chains | |----------|------------|----------|-------------|--------| | Yulia | | | | Chains | | Nadya | | | | | | Seva | | | Gilded Nuts | | | Lenya | Snowflakes | | | |
