Answer:
Based on the context clues, the character feels sad.
Explanation:
A context clue can be defined as a piece of information given by the author that can help the reader understand something.
In the excerpt we are studying here, it is possible to find some information that leads us to believe the character is sad. If the author had only described the girl staring out the window at the other children playing a game, we wouldn't be able to conclude enough. She could be tired, sad... She could even be excited about it.
The author, however, tells us she's asking herself if she will ever play with them and how they can be friends. If she is watching the other kids while feeling left out, she is most likely sad. The other options do not seem to match these context clues.
