Input: Read this: Comparsas are held throughout the week, consisting of large groups "of dancers dancing and traveling on the streets, followed by a Carrosa (carriage) where the musicians play. The Comparsa is a development of African processions where groups of devotees follow a given saint or deity during a particular religious celebration". One of the most popular comparsas of Fiesta de Carnaval is the male group comparsa, usually composed of notable men from the community who dress up in outlandish costumes or cross-dress and dance to compete for money and prizes. Other popular activities include body painting and flour fighting. "On the last day of Carnival painters flood the street to paint each other. This simply means that a mixture of water paint and water or raw eggs is used to paint people on the streets, the goal being to paint as many people as you can".
Question: What is used in some of the festive fights?

Output: flour

Input: Read this: All vertebrate brains share a common underlying form, which appears most clearly during early stages of embryonic development. In its earliest form, the brain appears as three swellings at the front end of the neural tube; these swellings eventually become the forebrain, midbrain, and hindbrain (the prosencephalon, mesencephalon, and rhombencephalon, respectively). At the earliest stages of brain development, the three areas are roughly equal in size. In many classes of vertebrates, such as fish and amphibians, the three parts remain similar in size in the adult, but in mammals the forebrain becomes much larger than the other parts, and the midbrain becomes very small.
Question: Which group of animals does the forebrain grow the largest?

Output: mammals

Input: Read this: The foundation has donated billions of dollars to help sufferers of AIDS, tuberculosis and malaria, protecting millions of children from death at the hands of preventable diseases. However, a 2007 investigation by The Los Angeles Times claimed there are three major unintended consequences with the foundation's allocation of aid. First, sub-Saharan Africa already suffered from a shortage of primary doctors before the arrival of the Gates Foundation, but "by pouring most contributions into the fight against such high-profile killers as AIDS, Gates grantees have increased the demand for specially trained, higher-paid clinicians, diverting staff from basic care" in sub-Saharan Africa. This "brain drain" adds to the existing doctor shortage and pulls away additional trained staff from children and those suffering from other common killers. Second, "the focus on a few diseases has shortchanged basic needs such as nutrition and transportation". Third, "Gates-funded vaccination programs have instructed caregivers to ignore even discourage patients from discussing ailments that the vaccinations cannot prevent".
Question: Vaccinations programs encouraged what

Output:
discourage patients from discussing ailments that the vaccinations cannot prevent".
