Q: Given scene/plot descriptions from movies or TV shows, and given a specific question about the scene, summarize the question into a title
In Interstellar, when Murph visits her brother and his wife, she notices that their son is coughing hard, and she offers to arrange a visit from a doctor for him. The brother and his wife refuse, however, even though she warns them their son will die otherwise. Did it signify anything? I thought that maybe it signified that there is an anti-science movement because of the blight. The brother certainly seemed to dislike his father and sister's scientific pursuits.
A:
Why did Murph's brother and his wife refuse a doctor for their son in Interstellar?
