Can a necessary assumption answer be a strengthening answer?

In other words, does a necessary assumption of an argument strengthens the argument? For example, if a stimulus argue that environmental factors caused X instead of genetics, would an answer choice like “environmental factors can sometimes cause X,” which I think is a NA, be strengthening the argument? I honestly think it does, though not much, since it shows that the argument is possible. And if it does, do all NA strengthen it’s pertaining arguments?

    I wouldn't say that necessary assumptions are strengthening the argument. They are just the essential component to the argument that was left out. Without that component, the argument fails. Sometimes the trap answer choice for NA questions will be something that strengthens the argument but is not necessary.

    In one of the videos JY mentions that strengthening is a super set of different LR questions, SA/PSA/NA. He said that in a sense SA/PSA/NA are strengthening. I would just err on the side of caution of thinking all NA strengthen
