• 2 and 3 are true. 1 is false; 15 lines are needed.

• Dude

You nailed it, Jimmy Barcus!

Statements 2 and 3 are true, statement 1 is false.

In statement 1, each line connects two beads and cannot be counted twice, so you need only 15 straight lines.

In statement 2, the pattern is alternately -3 and +1. The next number is 9, which is odd.

In statement 3, the “one block west” and “one block east” cancel out each other, and she ends up 2 blocks south from her house.

You are today’s winner.
