Q: We understand that paperclips are going to be provided materials, are we required to use the paperclips in the construction of the chopper? (section: Description / paragraph: 1 / sub-paragraph: / line: 1)
A: The event description indicates that the students will construct the chopper "...using one sheet of cardstock and one paper clip." This is interpreted to mean that both of those materials, and only those two materials will be used in the chopper.
Note that due to constraints of time, the event supervisor may select two of the three rotation/orientation options.
