Options:
- yes (both texts have the same meaning)
- no (there is significant difference in meaning between the two texts)

Examples:
text1: "Why do you behave like an asshole?"
text2: "Why do you act so bad?"
Answer: yes

text1: "This political party is a gang of idiots"
text2: "They just don’t know their stuff"
Answer: no

text1: "There is nothing dangerous here. People like Abraham Desta who try to create chaos are just opponents of the old system."
text2: "Nothing dangerous is happening. People like Abraham Desta who try to stir things up are just enemies of the previous regime."
Answer:'''
