The Internet was extensively used for passing information to aid rescue and recovery efforts. For example, the official news agency Xinhua set up an online rescue request center in order to find the blind spots of disaster recovery. After knowing that rescue helicopters had trouble landing into the epicenter area in Wenchuan, a student proposed a landing spot online and it was chosen as the first touchdown place for the helicopters[not in citation given]. Volunteers also set up several websites to help store contact information for victims and evacuees. On May 31, a rescue helicopter carrying earthquake survivors and crew members crashed in fog and turbulence in Wenchuan county. No-one survived.

Neutering refers to the sterilization of animals, usually by removal of the male's testicles or the female's ovaries and uterus, in order to eliminate the ability to procreate and reduce sex drive. Because of the overpopulation of dogs in some countries, many animal control agencies, such as the American Society for the Prevention of Cruelty to Animals (ASPCA), advise that dogs not intended for further breeding should be neutered, so that they do not have undesired puppies that may have to later be euthanized.
In neutering, what is removed in a male dog?

In 1821, Alexis Bouvard published astronomical tables of the orbit of Neptune's neighbour Uranus. Subsequent observations revealed substantial deviations from the tables, leading Bouvard to hypothesise that an unknown body was perturbing the orbit through gravitational interaction. In 1843, John Couch Adams began work on the orbit of Uranus using the data he had. Via Cambridge Observatory director James Challis, he requested extra data from Sir George Airy, the Astronomer Royal, who supplied it in February 1844. Adams continued to work in 1845–46 and produced several different estimates of a new planet.
What happened in February 1855?
A:
unanswerable
