3. Ramon was a participant in a clinical study to determine how much vitamin D is required
by healthy humans. During the study, Ramon consumed only a formula diet that was
nutritionally complete, except it did not contain vitamin D. Within a few weeks, he developed
signs and symptoms of vitamin D deficiency. At that point, researchers gave 5 mcg vitamin D
to Ramon each day for a week, but his signs and symptoms of the deficiency remained. The
next week, the scientists added 5 mcg vitamin D to his diet, so that his formula contained 10
mcg of the vitamin. By the end of that week, Ramon reported feeling much better. Based on
this information, the researchers concluded that Ramon's
A. daily required allowance for vitamin D was about 10 mcg.
B. RDA for vitamin D was 5 mcg, plus a margin of safety amount of 5 mcg.
C. AMDR for vitamin D was between 5 and 10 mcg.
D. requirement for vitamin D was 10 mcg.

4. Kayla was a participant in a clinical study to determine how much vitamin C cures scurvy,
the vitamin's deficiency disease. During the study, Kayla consumed only a formula diet that
was nutritionally complete, except it did not contain vitamin C. Within a few weeks, Kayla
developed scurvy. At that point, researchers gave 2 mg vitamin C to Kayla each day for a
week, but her signs and symptoms of scurvy remained. In the weeks that followed, the
scientists continued to increase Kayla's intake of the vitamin by 2 mg/week. After a week of
taking 10 mg of vitamin C/day, Kayla reported feeling much better. Based on this information,
the researchers concluded that Kayla's
A. EER for vitamin C was about 10 mg.
B. requirement for vitamin C was 10 mg.
C. AI for vitamin C was 100 mg, which was 10 times the amount that cured her case of
scurvy.
D. RDA for vitamin C was 10 mg, plus 15 mg as a margin of safety.

5. A group of 50 adult male humans were in a clinical study to determine how much niacin is
toxic. During the first two weeks of the study, members of the group consumed only a
formula diet that was nutritionally complete, except it contained 24 mg niacin, which is 1.5
times the RDA for niacin (males). At that point in the study, all members reported feeling fine,
and they could function normally. During the next week, they were given a formula that
contained 48 mg niacin. Within a few days of consuming this formula, 90% of the participants
reported feeling ill, and they complained of having upset stomachs and reddened facial skin.
At that point, researchers gave the subjects a formula that contain 16 mg niacin. After a week
of consuming the new formula, all participants reported feeling well again. Based on this
information, the researchers concluded that the
A. EER for niacin was 16 mg/day.
B. UL for niacin was between 24 and 48 mg/day.
C. human requirement for niacin is 16 mg/day.
D. AMDR for niacin is between 16 and 24 mg/day.

6. Josh was a participant in a clinical study to determine how much thiamin cures beriberi, the
vitamin's deficiency disease. During the study, Josh consumed only a formula diet that was
nutritionally complete, except it did not contain thiamin. Within a few weeks, Josh developed
beriberi. At that point, researchers gave 0.20 mg thiamin to Josh each day for a week, but his
signs and symptoms of beriberi remained. In the weeks that followed, the scientists continued
to increase Josh's intake of the vitamin by 0.2 mg/week. After a week of taking 0.6 mg
of thiamin/day, Josh reported feeling much better. Based on this information, the researchers
concluded that Josh's
A. RDA for thiamin was 0.6 mg/day.
B. UL for thiamin was 0.20 mg/day.
C. AMDR for thiamin was between 0.2 and 0.6 mg/day.

7. Recently, Miriah participated in a study that was designed to determine how much iron is
necessary to prevent iron deficiency. Within a few weeks of consuming an iron-free diet,
Miriah's red blood cells began to show signs that they lacked iron, and she began to complain
about feeling tired. At that point, the researcher added some iron to Miriah's food, so her daily
intake of the mineral would be 1 mg. After 1 week, the researchers checked the iron content
of Miriah's blood, and although it was higher than the earlier value, she still complained about
feeling tired. In the weeks that followed, the scientists continued to increase Miriah's iron
intake by 1 mg/week and check her for signs and symptoms of iron deficiency. After a week
of taking 6 mg of iron/day, she reported feeling like "her old self" and having plenty of
energy. Based on this information, the researchers concluded that Miriah's
A. UL for iron was 6 mg, plus 3 mg as a margin of safety.
B. RDA for iron was 6 mg.
C. body required 6 mg iron/day.
D. AMDR for iron was 6 mg/day.
