Array B has three rows and four columns, and cach of the twelve cells of B contains an integer. The content
of the cell in row r and column e is denoted B(r, c), where 1 <r < 3 and1<¢< 4. The top-left cell is
denoted B(1,1).
1. The following list contains sixteen claims. For cach of the sixteen claims in turn, determine whether the
claim is true or false. If you answer true, then briefly explain why the claim is true. If you answer false,
then briefly explain why the claim is falsc.
