Which one is true about the "real$-$life test" of your proposal?

$($see any Challenge Instructions file, section titles OPTIONAL Real$-$life Test of the proposed expansion strategy, comes around page $5$ or $6)$

Several of the partner companies added an option of trying to put the team ideas to a real$-$life test, namely try to get a contract for the proposed product in the proposed new market.

This is entirely optional: the team's decision to try or not to try finding a buyer for the product will not affect the team's performance evaluations.

If the team succeeds at finding a puyer and the deal goes through, the team members will receive a post$-$market commission $($usually $10-25\%$ of the contract $\sqrt[\phantom{2}]{7})$

All of the above are true
