Explanation:

1. For task 1, identify the specific action Lea altered in her lever setup.
2. For task 2, locate the outcome of her lever experiment.
3. For task 3, describe a modified lever setup and its resulting effect, mirroring the mentor text structure.

Answer:

1. Boxed text: First, I put the fulcrum near my hand.
2. Underlined text: It was hard to lift the book.
3. First, I moved the fulcrum close to the book. I placed the same book on the end of the yardstick farthest from me, and I pushed down on the lever. The end of the lever closest to me was much longer. Lifting the book felt very easy, and it rose up quickly when I pushed.
