[Q]: Extract the answer to the question from the following context. Question: What happens when officials are bribed? Context: Corruption facilitates environmental destruction. While corrupt societies may have formal legislation to protect the environment, it cannot be enforced if officials can easily be bribed. The same applies to social rights worker protection, unionization prevention, and child labor. Violation of these laws rights enables corrupt countries to gain illegitimate economic advantage in the international market.

[Q]: Extract the answer to the question from the following context. Question: What were the sources of income mentioned? Context: One of John's principal challenges was acquiring the large sums of money needed for his proposed campaigns to reclaim Normandy. The Angevin kings had three main sources of income available to them, namely revenue from their personal lands, or demesne; money raised through their rights as a feudal lord; and revenue from taxation. Revenue from the royal demesne was inflexible and had been diminishing slowly since the Norman conquest. Matters were not helped by Richard's sale of many royal properties in 1189, and taxation played a much smaller role in royal income than in later centuries. English kings had widespread feudal rights which could be used to generate income, including the scutage system, in which feudal military service was avoided by a cash payment to the king. He derived income from fines, court fees and the sale of charters and other privileges. John intensified his efforts to maximise all possible sources of income, to the extent that he has been described as "avaricious, miserly, extortionate and moneyminded". John also used revenue generation as a way of exerting political control over the barons: debts owed to the crown by the king's favoured supporters might be forgiven; collection of those owed by enemies was more stringently enforced.

[Q]: Extract the answer to the question from the following context. Question: What can vary when comparing a monkey to a bell pepper? Context: The genome size, and the number of genes it encodes varies widely between organisms. The smallest genomes occur in viruses (which can have as few as 2 protein-coding genes), and viroids (which act as a single non-coding RNA gene). Conversely, plants can have extremely large genomes, with rice containing >46,000 protein-coding genes. The total number of protein-coding genes (the Earth's proteome) is estimated to be 5 million sequences.

[Q]: Extract the answer to the question from the following context. Question: What was the old aspect ratio? Context: In November 2008, 720p HD support was added. At the time of the 720p launch, the YouTube player was changed from a 4:3 aspect ratio to a widescreen 16:9. With this new feature, YouTube began a switchover to H.264/MPEG-4 AVC as its default video compression format. In November 2009, 1080p HD support was added. In July 2010, YouTube announced that it had launched a range of videos in 4K format, which allows a resolution of up to 40963072 pixels. In June 2015, support for 8K resolution was added, with the videos playing at 76804320 pixels.
