Problem: The scientific evidence is mixed as to whether companionship of a dog can enhance human physical health and psychological wellbeing. Studies suggesting that there are benefits to physical health and psychological wellbeing have been criticised for being poorly controlled, and finding that "[t]he health of elderly people is related to their health habits and social supports but not to their ownership of, or attachment to, a companion animal."

People who have cats or dogs make fewer visits where?
The answer is the following: to the doctor

Problem: Beyonce's lighter skin color and costuming has drawn criticism from some in the African-American community. Emmett Price, a professor of music at Northeastern University, wrote in 2007, that he thinks race plays a role in many of these criticisms, saying white celebrities who dress similarly do not attract as many comments. In 2008, L'Oreal was accused of whitening her skin in their Feria hair color advertisements, responding that "it is categorically untrue", and in 2013, Beyonce herself criticized H&M for their proposed "retouching" of promotional images of her, and according to Vogue requested that only "natural pictures be used".
Which professor from Northeastern University wrote about how race correlates with these criticisms of Beyonce?

Problem: The Dominican Order was affected by a number of elemental influences. Its early members imbued the order with a mysticism and learning. The Europeans of the order embraced ecstatic mysticism on a grand scale and looked to a union with the Creator.

Though they are not called mystics, they are known for their piety toward God and their determination to live lives devoted to, and in emulation of, Him.
What did the Europeans of the Dominican Order bring to the group?

ecstatic mysticism
