A signed integer is the best option. In some systems, the value -1 can indicate that no combobox item is selected, so you need to allow for negative values.
Answer:
- The name of the project is C: Reversible Playmat
- The objectives are given in B
- The Sketch is given as D
- The Materials needed is listed in A
- The procedure is F
- Evaluation is E
Explanation:
You would find that the other matches are relatively easy save for B and F. The difference between the procedure is that the procedure is more detailed about what needs to be done.
Notice that F states exactly, the dimensions that need to be cut while B albeit wordier, gives a description of the end result only.
