In this task, you are given Wikipedia articles on a range of topics, we ask you to write a question based on the content of the articles that can be answered in a binary manner i.e. True or False.

[EX Q]: Dairy cattle -- To maintain lactation, a dairy cow must be bred and produce calves. Depending on market conditions, the cow may be bred with a ``dairy bull'' or a ``beef bull.'' Female calves (heifers) with dairy breeding may be kept as replacement cows for the dairy herd. If a replacement cow turns out to be a substandard producer of milk, she then goes to market and can be slaughtered for beef. Male calves can either be used later as a breeding bull or sold and used for veal or beef. Dairy farmers usually begin breeding or artificially inseminating heifers around 13 months of age. A cow's gestation period is approximately nine months. Newborn calves are removed from their mothers quickly, usually within three days, as the mother/calf bond intensifies over time and delayed separation can cause extreme stress on both cow and calf.

[EX Q]: Aldol condensation -- The first part of this reaction is an aldol reaction, the second part a dehydration--an elimination reaction (Involves removal of a water molecule or an alcohol molecule). Dehydration may be accompanied by decarboxylation when an activated carboxyl group is present. The aldol addition product can be dehydrated via two mechanisms; a strong base like potassium t-butoxide, potassium hydroxide or sodium hydride in an enolate mechanism, or in an acid-catalyzed enol mechanism. Depending on the nature of the desired product, the aldol condensation may be carried out under two broad types of conditions: kinetic control or thermodynamic control.
[EX A]: can aldol condensation take place in acidic medium

[EX Q]: Fez (That '70s Show) -- Valderrama has stated that he fabricated the accent he used on the show so that no one could identify which country his character is from, a mystery the show creators deliberately kept a secret.
[EX A]:
