[EX Q]: Passage: 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]: Passage: Emma Swan -- Arriving in the Underworld, Emma is contacted by Neal Cassidy, who warns to turn back, advice Emma chooses to ignore. She and the others later discover that the Underworld is for those with unfinished business, and they decide to help others move on, while they search for Hook. With the help of Hook's ex-girlfriend Milah, Emma manages to retrieve Hook from Hades's captivity. However, she is unable to split her heart, as Hades has decided that she, Regina, and Snow are to remain behind for freeing the souls of Prince Henry, Hercules, and Megara. It is discovered that the only way they would have a chance to return to the ``Overworld'' with Hook is by overthrowing Hades. In order to defeat Hades, Emma and Hook receive help from Hook's brother Liam; however, it is soon discovered that Liam betrayed them after being blackmailed by Hades. Fortunately, Henry agrees to help undo Liam's work by using his powers as the Author. Later, when Emma and Hook try to perform the heartsplit, they are informed by Hades that Hook's body has been dead for too long and is decaying, making him unable to come back to life. When Emma and Hook go into the depths of the Underworld to find ambrosia, something that would save Hook, they are faced with a True Love test, which they pass when Emma chooses Hook over her own heart, only to realize that Hades had tricked them and destroyed the ambrosia, and Hook tells Emma to leave him in the Underworld, as time is running out for her to go through the open portal. Emma objects, saying that she came to the Underworld to save Hook, and she wasn't leaving without him. Hook eventually gets her to say her goodbyes and she does, only to find out that Hades had trapped her and her family in the library using magic. Emma and Regina work together to use their own magic to counteract it. They all go through the portal, and while Emma has second thoughts about leaving Hook, she is persuaded to go by her father. When they get back to Storybrooke, Zelena is informed by Regina and Robin that Hades tried to trap them in the Underworld, but she brushes off the information and is upset with her sister. She talks to Hades about having the life she wants, which is just a simple picket fence life. However, Hades wants a whole kingdom. Robin and Regina break into the mayor's house, where Zelena and Hades are, trying to get Robin's daughter back from Zelena. Emma, distraught and unable to grieve Hook's death, tries to break down the protection spell surrounding the house, but Zelena uses her magic to stop her. Hades is about to use the Olympian Crystal to ``end'' Regina, but Robin steps in front of her, taking the blow, which kills him. Hades tries to pressure Zelena into killing Regina, but she stabs Hades instead.
