Correct Answer: decided

Solution : The correct option is the second option.

Decided means they made a choice or came to a conclusion. In this context, it implies that the nerdy linguists reached a decision or agreement about something related to making fun of the syntax, perhaps deciding on a specific approach or manner in which to do so.

The meanings of the other options are as follows:

• Braided: This means weaving strands together, often referring to hair or materials being intertwined.
• Stalked: This means to pursue or follow someone closely, usually with the intent to observe or harm them.
• Traded: This means exchanging goods, services, or ideas between two parties.

Therefore, the complete sentence would be: "My friends, being incredibly nerdy linguists, decided to make fun of the syntax."
