   Astronauts who have lived in the weightless environment of space have exhibited decreases in bone density

   We knew that "preventing osteo requires weight-bearing exercise". So if you're in a weightless environment, you can't easily do weight-bearing exercise, and so you might start to develop osteoporosis, which is a decrease in bone density.

   Why this is right

   This answer choice conflicts with what we were told. We were told that a special diet (low protein, lots of fruits/veggies, a bit of meat/dairy) was essential to preventing osteoporosis. That means, if no special diet, can't prevent osteoporosis This answer choice is talking about a scenario in which you do not have a special diet, but it's still effective at preventing osteoporosis.

   Populations in countries with the lowest per capita rates of protein consumption have some of the

   This reinforces the idea that low-protein is required to prevent osteoporosis. Countries with lower protein consumption have lower osteoporosis rates. In order to prevent osteoporosis, you need 1. low protein 2. lots of fruit veggies 3. a modest amount of meat and dairy 4. weight-bearing exercise

   This reinforces the first claim, that high-calcium is not the way to prevent osteoporosis. After all, look at these people who eat tons of calcium. They have some of the most osteoporosis of anyone!

   The incidence of osteoporosis is unusually low among strict vegetarians with

   This one's the weirdest of the four we're eliminating. It reinforces the connection between low-protein and low incidence of osteoporosis. But the strict vegetarian thing seems to go against the idea that "a minimum amount of meat and dairy" are required. Given that a strict vegetarian diet would have no meat, it seems like in conditional thinking this would be a deal breaker. But apparently LSAT wants us to think of this more in a squishy causal way -- like, you don't need the set of all four things to get some benefit in preventing osteoporosis. It's an abuse of the strict meaning of "essential", but this answer is still closer to helping the author than the correct answer is. The correct answer pretty much contradicts something. This one is just a bit muddled. Saying we have #1 but #3 are still seeing unusually low rates of osteoporosis does at least have a supporting component to it.
