In rheumatoid arthritis, the body’s immune system misfunctions by attacking healthy cells in the joints causing the release of a hormone that in turn causes pain and swelling.
Statements
causal chain (causing / that in turn causes)
In rheumatoid arthritis: immune system hormone pain and attacks healthy >> is released >> swelling joint cells
comparison (misfunctions vs. normally)
Usually, that hormone is only released when we're injured or infected.
causal (inhibits)
new med >> hormone not released
Evaluate
We have some causality, so the correct answer will probably be rewarding our ability to understand the cause/effect relationships presented.
The big Overlapping Concept that's in all three claims is this hormone.
The first two sentences feel more like general truths / rules, and the last claim feels more like a specific fact that the test wants us to apply this general knowledge to.
If we're told that this new drug inhibits the hormone, would we be able to infer anything else about it?
We know in the case of arthritis, the whole point of inhibiting the hormone would be to lessen the pain and swelling of that condition. But how would this drug affect the 2nd sentence?
It seems like the body usually releases this hormone when we get injured or get an infection (which is why we're used to feeling pain and swelling when we get injured or have an infection). So if this drug keeps the hormone from releasing, would we still feel pain or swelling after we get injured or infected?
Goal
Let's keep a flexible mind, but the correct answer might address what this new medication would do in relation to injuries / infections (it might keep us from feeling the normal pain/swelling associated with them).
