Problem: 863. INGREDIENTS.--The remains of a boiled calf's head, 1-1/2 pint of the liquor in which the head was boiled, 1 blade of pounded mace, 1 onion minced, a bunch of savoury herbs, salt and white pepper to taste, thickening of butter and flour, the yolks of 2 eggs, 1 tablespoonful of lemon-juice, forcemeat balls. _Mode_.--Remove all the bones from the head, and cut the meat into nice square pieces. Put 1-1/2 pint of the liquor it was boiled in into a saucepan, with mace, onion, herbs, and seasoning in the above proportion; let this simmer gently for 3/4 hour, then strain it and put in the meat. When quite hot through, thicken the gravy with a little butter rolled in flour, and, just before dishing the fricassee, put in the beaten yolks of eggs and lemon-juice; but be particular, after these two latter ingredients are added, that the sauce does not boil, or it will curdle. Garnish with forcemeat balls and curled slices of broiled bacon. To insure the sauce being smooth, it is a good plan to dish the meat first, and then to add the eggs to the gravy: when these are set, the sauce may be poured over the meat.

Question: "Is the meat removed from the bone before or after boiling?"

Answer: "After boiling"

OPTIONS:
- no
- yes
Answer: yes

Problem: Early in chapter 5 we introduced, along with Khalid Sheikh Mohammed, two other men who became operational coordinators for al Qaeda: Khallad and Nashiri. As we explained, both were involved during 1998 and 1999 in preparing to attack a ship off the coast of Yemen with a boatload of explosives. They had originally targeted a commercial vessel, specifically an oil tanker, but Bin Laden urged them to look for a U.S.warship instead. In January 2000, their team had attempted to attack a warship in the port of Aden, but the attempt failed when the suicide boat sank. More than nine months later, on October 12,2000, al Qaeda operatives in a small boat laden with explosives attacked a U.S. Navy destroyer, the USS Cole. The blast ripped a hole in the side of the Cole, killing 17 members of the ship's crew and wounding at least 40. The plot, we now know, was a full-fledged al Qaeda operation, supervised directly by Bin Laden. He chose the target and location of the attack, selected the suicide operatives, and provided the money needed to purchase explosives and equipment. Nashiri was the field commander and managed the operation in Yemen. Khallad helped in Yemen until he was arrested in a case of mistaken identity and freed with Bin Laden's help, as we also mentioned earlier. Local al Qaeda coordinators included Jamal al Badawi and Fahd al Quso, who was supposed to film the attack from a nearby apartment. The two suicide operatives chosen were Hassan al Khamri and Ibrahim al Thawar, also known as Nibras. Nibras and Quso delivered money to Khallad in Bangkok during Khallad's January 2000 trip to Kuala Lumpur and Bangkok. In September 2000, Bin Laden reportedly told Nashiri that he wanted to replace Khamri and Nibras. Nashiri was angry and disagreed, telling others he would go to Afghanistan and explain to Bin Laden that the new operatives were already trained and ready to conduct the attack. Prior to departing, Nashiri gave Nibras and Khamri instructions to execute the attack on the next U.S.warship that entered the port of Aden.

Question: "Why did the team avert from attacking an oil tanker and attempt to attack a warship?"

Answer: "Bin Laden urged them to look for a U.S.warship instead"

Problem: Mechanical energy is a combination of the energy of motion or position. This type of energy describes objects that are moving or could move. A moving ball can have energy from motion. An arrow can also have the energy of motion. Both are types of mechanical energy. Can you think of some other examples? Where does the energy of motion come from? It comes from the energy created by position. This energy is stored energy. This means it is not moving yet, but it has the potential to move. How can you store energy? The arrow gains energy from the drawn bow. As the arrow is released, the bow releases its stored energy and puts the arrow into motion. Can you think of some other ways to store energy using position?

Question: "What kind of energy is created by position?"

Answer: "Mechanical energy"

OPTIONS:
- no
- yes
Answer:
no
