Company X and Company Y have each been building a rocket ship able to travel to Mars. After five years of design and construction, the rocket ships have been unveiled to the public, which instantly notices the rocket ships are so similar in design as to be indistinguishable. Ttherefore, one of the companies must have had information pertaining to the design of the other rocket ship.
The statement "Each space ship uses a different color scheme, which matches that of each company's logo" would most call in to question the validity of the argument.
