Question

How does Aunt Polly know that Tom is lying about skipping school?

His shirt collar feels damp to Aunt Polly
Sid confesses that he's skipped school too.
His hair is still wet from the pond.
His collar has the wrong color thread.

Answer 1

Your answer is:

D. His collar has the wrong color thread.

Here is why:

When he skipped school, he went for a swim, and had to sew the collar of his shirt back on. Instead of using white thread to cover it up, he used black thread. And Aunt Polly was suspicious.
