CR 1 During the production of orange juice, calcium is sometimes added as a nutritional supplement. Certain individuals are allergic to calcium, and drinking orange juice fortified with calcium can cause an allergic reaction. Fortunately, some types of orange juice do not have calcium added during production, so calcium-allergic individuals can drink these orange juices without inducing an allergic reaction to calcium.
Which of the following is an assumption on which the argument depends?
(A) There are no other substances besides calcium that are typically present in orange juice that cause allergic reactions.
(B) Orange juice has the same nutritional value whether calcium is added or not.
(C) Calcium-allergic individuals cannot ingest any calcium without having an allergic reaction.
(D) Calcium is often added to other beverages besides orange juice.
(E) In orange juice that does not have calcium added during production, calcium is not naturally present in quantities that cause an allergic reaction.

CR 2 Herbal tea has become a popular product and is offered by a number of brands. An investigation showed that out of the 7 brands of tea sold at an average-sized supermarket, all included preservatives and added chemicals for flavor and color. It can be stated, therefore, that in order to drink a truly healthy herbal tea, the ingredients should be collected from a natural source.
Which of the following, if true, supports the argument's conclusion?
(A) The increase in the popularity of herbal teas is a result of the emergence of the organic product market.
(B) Average-size supermarkets usually offer products with the highest level of consumer awareness.
(C) Herbs grown in a garden, with water alone, contain none of the food-industry chemicals that have been proven to disrupt digestion.
(D) Some people add large amounts of sugar to herbal tea, increasing the amount of calories in the beverage.
(E) Buying tea herbs directly from farms does not rule out the possibility that they contain residue from pesticides or hormones.
