As cellular metabolism/energy production requires oxygen, potentially damaging (e.g., mutation causing) compounds known as free radicals can form. Most of these are oxidizers (i.e., acceptors of electrons) and some react very strongly. For the continued normal cellular maintenance, growth, and division, these free radicals must be sufficiently neutralized by antioxidant compounds. Recently, some researchers suggested an interesting theory of evolution of dietary antioxidants. Some are produced by the human body with adequate precursors (glutathione, Vitamin C), and those the body cannot produce may only be obtained in the diet via direct sources (Vitamin C in humans, Vitamin A, Vitamin K) or produced by the body from other compounds (Beta-carotene converted to Vitamin A by the body, Vitamin D synthesized from cholesterol by sunlight). Phytochemicals (Section Below) and their subgroup, polyphenols, make up the majority of antioxidants; about 4,000 are known. Different antioxidants are now known to function in a cooperative network. For example, Vitamin C can reactivate free radical-containing glutathione or Vitamin E by accepting the free radical itself. Some antioxidants are more effective than others at neutralizing different free radicals. Some cannot neutralize certain free radicals. Some cannot be present in certain areas of free radical development (Vitamin A is fat-soluble and protects fat areas, Vitamin C is water-soluble and protects those areas). When interacting with a free radical, some antioxidants produce a different free radical compound that is less dangerous or more dangerous than the previous compound. Having a variety of antioxidants allows any byproducts to be safely dealt with by more efficient antioxidants in neutralizing a free radical's butterfly effect.

What are oxidizers?
Output: acceptors of electrons

Input: Pub
The Lost Pubs Project listed 28,095 closed pubs on 21 April 2015, with photographs of many. In 2015 the rate of pub closures came under the scrutiny of Parliament in the UK, with a promise of legislation to improve relations between owners and tenants.

What did Parliament promise to pass as a result of increased pub closures?
Output: legislation to improve relations between owners and tenants

Input: Pub
From the mid-19th century on the opening hours of licensed premises in the UK were restricted. However licensing was gradually liberalised after the 1960s, until contested licensing applications became very rare, and the remaining administrative function was transferred to Local Authorities in 2005.

In what century were the operating hours of drinking establishments first limited?
Output: 19th

Input: Beyonce
Beyonce Giselle Knowles was born in Houston, Texas, to Celestine Ann "Tina" Knowles (nee Beyince), a hairdresser and salon owner, and Mathew Knowles, a Xerox sales manager. Beyonce's name is a tribute to her mother's maiden name. Beyonce's younger sister Solange is also a singer and a former member of Destiny's Child. Mathew is African-American, while Tina is of Louisiana Creole descent (with African, Native American, French, Cajun, and distant Irish and Spanish ancestry). Through her mother, Beyonce is a descendant of Acadian leader Joseph Broussard. She was raised in a Methodist household.

Beyonce is a descendent of what Arcadian leader?
Output:
Joseph Broussard
