Answer to Question 1

a. Use the same length of string for both ellipses. For the second, move the tacks further apart to increase the eccentricity.
b. Keep the tacks the same distance apart for both ellipses. For the first, half the length of the string and then draw the ellipse. For the second, use the original length of the string.

Answer to Question 2

TRUE
