A wrestling match

"So you wanted to join our group huh" the taller girl says. "Well to be on our teem you need to be strong, we lost a lot of people for not being strong" has also made us stronger and ruthless. So if you want to survive tonight you'll have to beat one of us in a fight/wrestling match. If you win you will get access to our supplies, maybe more. But if you loose we will knock you out and toss you overboard to die. So choose which one of us you want to fight". Be warned i may be stronger than my sister, but she is more skilled at fighting". So who do you choose.

The tall girl seems really powerful, she looks like she could snap you in half if she wanted. Plus she's half a foot taller than you so she seems to have pretty big advantages.

The other girl is shorter than her sister but she is still taller than you. She also has some really big assets that will probably make it hard to focus on the match. Plus she is more skilled than her sister so just by looking at you she probably knows how to beat you. She also looks very strong. Not to the level of her sister but strong enough to perform any move she wants to.
