what if an option is available as follows:

'elected to retire early rather than face'. Will it then be treated a correct choice?

Hi Silvia, As a general rule, if you are asked to find the 'least' that a value can be, maximize all the other values. Conversely, if you're trying to find the 'most' that a value can be, minimize all the other values. In this case, to find the least possible score that a team could have earned, ma...
