The problem: Answer a question about this article:
Most ingested uranium is excreted during digestion. Only 0.5% is absorbed when insoluble forms of uranium, such as its oxide, are ingested, whereas absorption of the more soluble uranyl ion can be up to 5%. However, soluble uranium compounds tend to quickly pass through the body, whereas insoluble uranium compounds, especially when inhaled by way of dust into the lungs, pose a more serious exposure hazard. After entering the bloodstream, the absorbed uranium tends to bioaccumulate and stay for many years in bone tissue because of uranium's affinity for phosphates. Uranium is not absorbed through the skin, and alpha particles released by uranium cannot penetrate the skin.
Where does uranium accumulate in the body?
****
The answer: bone tissue

The concept of race in Brazil is complex. A Brazilian child was never automatically identified with the racial type of one or both of his or her parents, nor were there only two categories to choose from. Between an individual of unmixed West African descent and a very light mulatto individual, more than a dozen racial categories were acknowledged, based on various combinations of hair color, hair texture, eye color, and skin color. These types grade into each other like the colors of the spectrum, and no one category stands significantly isolated from the rest. In Brazil, people are classified by appearance, not heredity.
How are people in Brazil classified?
****
The answer: by appearance
