Cap'n, we're faced with a question. Should we keep our all-female crew purity, and only admit males on special rules? Or should we take advantage of the fact that trained male soldiers are easily available for hire? The former would require us to invest substantial research into finding a steady supply of Uber gals (Uber boys won't likely want to work for us anyway). This will only affect hiring on the open market, not any alternative sources we can find.
This situation presents us with two choices. Diverging topics of research are displayed next to each other and indicated with '?' signs. Researching one topic will remove the other - permanently. We will surely face more of such dilemmas in the future.
