Problem: Please answer a question about the following article about Buckingham Palace:
Possibly the first house erected within the site was that of a Sir William Blake, around 1624. The next owner was Lord Goring, who from 1633 extended Blake's house and developed much of today's garden, then known as Goring Great Garden. He did not, however, obtain the freehold interest in the mulberry garden. Unbeknown to Goring, in 1640 the document "failed to pass the Great Seal before King Charles I fled London, which it needed to do for legal execution". It was this critical omission that helped the British royal family regain the freehold under King George III.
Who built the first house on the site?
A: Sir William Blake

Problem: Please answer a question about the following article about Antenna (radio):
Gain is a parameter which measures the degree of directivity of the antenna's radiation pattern. A high-gain antenna will radiate most of its power in a particular direction, while a low-gain antenna will radiate over a wider angle. The antenna gain, or power gain of an antenna is defined as the ratio of the intensity (power per unit surface area) radiated by the antenna in the direction of its maximum output, at an arbitrary distance, divided by the intensity radiated at the same distance by a hypothetical isotropic antenna which radiates equal power in all directions. This dimensionless ratio is usually expressed logarithmically in decibels, these units are called "decibels-isotropic" (dBi)
What is the meaning of intensity?
A: power per unit surface area
Problem: Please answer a question about the following article about Queen Victoria:
On 29 May 1842, Victoria was riding in a carriage along The Mall, London, when John Francis aimed a pistol at her but the gun did not fire; he escaped. The following day, Victoria drove the same route, though faster and with a greater escort, in a deliberate attempt to provoke Francis to take a second aim and catch him in the act. As expected, Francis shot at her, but he was seized by plain-clothes policemen, and convicted of high treason. On 3 July, two days after Francis's death sentence was commuted to transportation for life, John William Bean also tried to fire a pistol at the Queen, but it was loaded only with paper and tobacco and had too little charge. Edward Oxford felt that the attempts were encouraged by his acquittal in 1840. Bean was sentenced to 18 months in jail. In a similar attack in 1849, unemployed Irishman William Hamilton fired a powder-filled pistol at Victoria's carriage as it passed along Constitution Hill, London. In 1850, the Queen did sustain injury when she was assaulted by a possibly insane ex-army officer, Robert Pate. As Victoria was riding in a carriage, Pate struck her with his cane, crushing her bonnet and bruising her forehead. Both Hamilton and Pate were sentenced to seven years' transportation.
Who made two unsuccessful attempts on Queen Victoria's life in 1842?
A:
John Francis
