Problem: Asphalt:

Roofing shingles account for most of the remaining asphalt/bitumen consumption. Other uses include cattle sprays, fence-post treatments, and waterproofing for fabrics. Asphalt/bitumen is used to make Japan black, a lacquer known especially for its use on iron and steel, and it is also used in paint and marker inks by some graffiti supply companies to increase the weather resistance and permanence of the paint or ink, and to make the color much darker.[citation needed] Asphalt/bitumen is also used to seal some alkaline batteries during the manufacturing process.

Besides weather resistance, why else is Japan black used in paints?

A: permanence

Problem: Queen Victoria:

On 17 March 1883, she fell down some stairs at Windsor, which left her lame until July; she never fully recovered and was plagued with rheumatism thereafter. Brown died 10 days after her accident, and to the consternation of her private secretary, Sir Henry Ponsonby, Victoria began work on a eulogistic biography of Brown. Ponsonby and Randall Davidson, Dean of Windsor, who had both seen early drafts, advised Victoria against publication, on the grounds that it would stoke the rumours of a love affair. The manuscript was destroyed. In early 1884, Victoria did publish More Leaves from a Journal of a Life in the Highlands, a sequel to her earlier book, which she dedicated to her "devoted personal attendant and faithful friend John Brown". On the day after the first anniversary of Brown's death, Victoria was informed by telegram that her youngest son, Leopold, had died in Cannes. He was "the dearest of my dear sons", she lamented. The following month, Victoria's youngest child, Beatrice, met and fell in love with Prince Henry of Battenberg at the wedding of Victoria's granddaughter Princess Victoria of Hesse and by Rhine to Henry's brother Prince Louis of Battenberg. Beatrice and Henry planned to marry, but Victoria opposed the match at first, wishing to keep Beatrice at home to act as her companion. After a year, she was won around to the marriage by Henry and Beatrice's promise to remain living with and attending her.

Who did Queen Victoria write a biography about that was never published?
---
A: John Brown

Problem: Botany:

Botany, also called plant science(s) or plant biology, is the science of plant life and a branch of biology. A botanist or plant scientist is a scientist who specializes in this field. The term "botany" comes from the Ancient Greek word (botane) meaning "pasture", "grass", or "fodder"; is in turn derived from (boskein), "to feed" or "to graze". Traditionally, botany has also included the study of fungi and algae by mycologists and phycologists respectively, with the study of these three groups of organisms remaining within the sphere of interest of the International Botanical Congress. Nowadays, botanists study approximately 400,000 species of living organisms of which some 260,000 species are vascular plants and about 248,000 are flowering plants.

Does botany only study plants?
---
A: included the study of fungi and algae

Problem: FA Cup:

In the early years of coverage the BBC had exclusive radio coverage with a picture of the pitch marked in the Radio Times with numbered squares to help the listener follow the match on the radio. The first FA Cup Final on Radio was in 1926 between Bolton Wanderers and Manchester City but this was only broadcast in Manchester, the first national final on BBC Radio was between Arsenal and Cardiff in 1927. The first final on BBC Television was in 1937 in a match which featured Sunderland and Preston North End but this was not televised in full. The following season's final between Preston and Huddersfield was covered in full by the BBC. When ITV was formed in 1955 they shared final coverage with the BBC in one of the only club matches shown live on television, during the 1970s and 1980s coverage became more elaborate with BBC and ITV trying to steal viewers from the others by starting coverage earlier and earlier some starting as early as 9 a.m. which was six hours before kick off. Nowadays, this continues with Setanta and ESPN having all-day broadcasts from Wembley, but terrestrial TV coverage usually begins two hours before kick off. The sharing of rights between BBC and ITV continued from 1955 to 1988, when ITV lost coverage to the new Sports Channel which later became Sky Sports.

What clubs competed in the match?

Bolton Wanderers and Manchester City
