@SeonAh-Lee,

The passage tells that CJD is a result of an extensive nerve cell damage (lines 15-17). The passage also tells us that the damage occurs because prions that exhibit the abnormal shape have an ability to replicate themselves by initiating a chain reaction that induces normally shaped prions to transform themselves upon contact, and this cascade of transformations produces a thread like plaque that collects in the brain and destroys nerve cells (lines 30-39). Since the brain damage associated with CJD is a result of this cascading transformation, we can infer that if prions were unable to reproduce themselves, they would not cause the nerve cell damage.

Let me know if you have any further questions.
