Read the information at the right. Let me know what you decide.

@WriteTeacher I think it is: used when comparing things, situations, or people and showing how they are different. But I may be wrong.

Yes! It's a conjunction used for those reasons.

Okay thank you! :)

Read the passage below.

When I first saw my friends playing soccer at recess, I was not sure I wanted to play. I had never played soccer before and, therefore, was not sure I would be very good at it. I decided to observe the game for a while before deciding, so I sat on the bench and watched my friends run around, laugh, and cheer for each other. They all appeared to be having a great time. Finally, I decided to get on the field and give the game of soccer a try.
Which signal word indicates what event happened the last?

I'll be happy to check what you think.

Certainly! To determine the purpose of the signal word "while" in this passage, we need to understand its function in the sentence. "While" is a conjunction that is used to indicate a contrast, presenting two contrasting ideas or pieces of information.

In this case, the passage states that crocodiles and alligators have different snout shapes. The first part of the sentence describes crocodiles with longer, pointed, V-shaped snouts. The word "while" is then used to introduce a contrast with the information that follows, stating that alligators generally have wider, rounder, U-shaped snouts.

Therefore, the purpose of the signal word "while" in this passage is to show the contrast or difference in snout shapes between crocodiles and alligators.
