Early Investor Or Company Co-founder?

In the ‘Rich, Richer and SuperRich’ quiz (July), the answer to question 7 is incorrect.

Elon Musk was not a co-founder of the Tesla company. He was an early investor. The company was founded by Martin Eberhard and Marc Tarpenning. They secured Musk as an early investor and he eventually joined the company and then took over the management.
