3 Say true, false or I don't know. 1) There were no pictures in the book Alice's sister was reading. 2) Alice liked that book very much. 3) Alice dropped the jar when she saw that there was no marmalade in it. 4) Dinah (Alice's cat) was three years old.

I need more context to accurately answer "true", "false", or "I don't know". I can provide possible answers based on my knowledge of the story and common sense. 1) There were no pictures in the book Alice's sister was reading. True. At the beginning of the story, Alice is bored because the book her sister is reading has no pictures. 2) Alice liked that book very much. False. She was bored with the book. 3) Alice dropped the jar when she saw that there was no marmalade in it. I don't know. This event is not explicitly mentioned in the parts of the story I have access to, so I cannot definitively say if it's true or false. 4) Dinah (Alice's cat) was three years old. I don't know. The cat's age is not specified.
