Okay, so for this woman says, by sex and nationality, who had the greatest increase in life expectancy between nineteen fifty five and nineteen ninety. So what we're gonna do is we're going to go through each of the choices and see what the increase in life expectancy this. So let's go ahead and look at the Korean female. So from nineteen fifty five to nineteen ninety, we're going to be looking at second one because that's for females. Korea is the lowest line. So in any thirty five that's around, I would say that's around like fifty. So we're going from fifty all the way to something like seventy five in nineteen ninety. It's not stripped. The Korean males, Korean males go from about of forty. That's a forty nine for that one all the way to about sixty six at the end. Okay, so then, for the Costa Rican families, females, we know it's going to be the second line over here. So in nineteen forty five, it was around fifty eight. No increases all the way to about seventy six. I can see them for the Costa Rican males That's over here, so over here will have excuse me. Increase of from fifty seven all the way through about seventy three. So now if we're looking for the greatest increase, we have to find the difference between these and see how many years increase it wass for the Korean females, that's about twenty five. Her Korean males sixty six minus forty nine, is about seventeen or the Costa Ric and females. It's going to be seventy six minus fifty eight, just about eighteen. For the Costa Rican males, it's gonna be seventy three minus fifty seven, which is about eighteen as well. So Korean females have the greatest increase in life expectancy between nineteen fifty five in nineteen ninety.
