These questions are killing my score. I know how to answer them from a foundational standpoint but something is going wrong in my application. I just keep getting them wrong. Mainly level 4/5, sometimes 3, but not as frequently.

This question is still tripping me up, even after I have reviewed it. Can someone break the answer down for me? The explanation I seen isn't doing it for me.

Researcher: Research has shown that inhaling the scent of lavender has measurable physiological effects tending to reduce stress. It is known that intense stress can impair the immune system, making one more susceptible to illness. Therefore, it is likely that the incidence of illness among those who regularly inhale the scent of lavender is reduced by this practice.

Which one of the following is an assumption that the researcher's argument requires?

• A Many, if not all, of the scents that have a tendency to reduce susceptibility to illness do so, at least in part, by reducing stress.
• B Some people who regularly inhale the scent of lavender would otherwise be under enough stress to impair their immune systems.
• C At least some people who use the scent of lavender to induce relaxation and reduce stress are no more susceptible to illness than average.
• D In anyone for whom the scent of lavender reduces susceptibility to illness, it does so primarily by reducing stress.
• E Reduced stress diminishes susceptibility to illness only for people who are under enough stress to impair their immune systems to at least some degree.
