[EX Q]: Question: Is patient satisfaction biased by renovations to the interior of a primary care office : a pretest-posttest assessment?
Answer: Renovating the interior of a primary care office was associated with improved patient satisfaction, including satisfaction in domains otherwise unchanged. Physician skills and patient satisfaction sometimes depend on surrounding factors that may bias the ability of patients to assess the quality of medical care.

[EX Q]: Question: Does cheating explain selective differences at high and low relatedness in a social amoeba?
Answer: These results suggest that social competition and something beyond solitary growth differences occurs during the vegetative stage when amoebae eat bacteria and divide by binary fission. The high degree of repeatability of our results indicates that these effects are strong and points to the importance of new approaches to studying interactions in D. discoideum.
[EX A]: no
