Answer 2

In the given expressions, the symbol "и" seems to be used to represent logical "AND" operations. Also, the symbol ">" represents the "greater than" operator, and the symbol "<" represents the "less than" operator.

Let's evaluate each expression step by step:

1. 5 < 9 and 3 < 4: Both conditions are true since 5 is less than 9 and 3 is less than 4.

2. 3 > 1 and 5 > -2: Both conditions are true since 3 is greater than 1 and 5 is greater than -2.

3. 2 < 3 and 4 < 7: Both conditions are true since 2 is less than 3 and 4 is less than 7.

4. 4 > 1 and 7 > 5 < 9 and 2 < 4: The first part, 4 > 1, is true, and the second part, 7 > 5, is also true. However, the third part, 5 < 9, is true but not relevant to the preceding parts. So, the correct expression would be: (4 > 1) and (7 > 5) and (2 < 4). All conditions are true since 4 is greater than 1, 7 is greater than 5, and 2 is less than 4.

5. 0.5 < 3 and 4 < 5: Both conditions are true since 0.5 is less than 3 and 4 is less than 5.

To summarize, all the given expressions are true based on the evaluation of each condition within them.
