I want to know the answer to the following question:
Who says the bond of blood between mother and son is more meaningfu than the bond of marriage?
All the background I'm provided with is that "Apollo and the Furies argue about whether the matricide was justified; Apollo holds that the bond of marriage is sacred and Orestes was avenging his father, whereas the Erinyes say that the bond of blood between mother and son is more meaningful than the bond of marriage.". Is that enough to answer the question?
Answer: yes
