Problem: Race (human categorization):

Other researchers point out that finding a difference in disease prevalence between two socially defined groups does not necessarily imply genetic causation of the difference. They suggest that medical practices should maintain their focus on the individual rather than an individual's membership to any group. They argue that overemphasizing genetic contributions to health disparities carries various risks such as reinforcing stereotypes, promoting racism or ignoring the contribution of non-genetic factors to health disparities. International epidemiological data show that living conditions rather than race make the biggest difference in health outcomes even for diseases that have "race-specific" treatments. Some studies have found that patients are reluctant to accept racial categorization in medical practice.

What have some studies found patients reluctant to accept in medical practice?

A: racial categorization

Problem: BeiDou Navigation Satellite System:

In 2007, the official Xinhua News Agency reported that the resolution of the BeiDou system was as high as 0.5 metres. With the existing user terminals it appears that the calibrated accuracy is 20m (100m, uncalibrated).

According to which news agency was the BeiDou resolution as high as .7 metres?
---
A: unanswerable

Problem: Hokkien:

The pronounced divergence between literary and colloquial pronunciations found in Hokkien dialects is attributed to the presence of several strata in the Min lexicon. The earliest, colloquial stratum is traced to the Han dynasty (206 BCE - 220 CE); the second colloquial one comes from the period of the Southern and Northern Dynasties (420 - 589 CE); the third stratum of pronunciations (typically literary ones) comes from the Tang Dynasty (618907 CE) and is based on the prestige dialect of Chang'an (modern day Xi'an), its capital.

Colloquial stratum can be traced to several strata in what lexicon?
---
A: Min

Problem: Genome:

The proportion of non-repetitive DNA is calculated by using the length of non-repetitive DNA divided by genome size. Protein-coding genes and RNA-coding genes are generally non-repetitive DNA. A bigger genome does not mean more genes, and the proportion of non-repetitive DNA decreases along with increasing genome size in higher eukaryotes.

What is the number of protein-coding genes divided by to get the proportion of non-repetitive DNA?
