Teacher: In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.
Teacher: Now, understand the problem? If you are still confused, see the following example:
Passage: Nearing London, Oliver encounters Jack Dawkins, a pickpocket more commonly known by the nickname the "Artful Dodger", and his sidekick, a boy of a humorous nature named Charley Bates, but Oliver's innocent and trusting nature fails to see any dishonesty in their actions. The Dodger provides Oliver with a free meal and tells him of a gentleman in London who will "give him lodgings for nothing, and never ask for change". Grateful for the unexpected assistance, Oliver follows the Dodger to the "old gentleman's" residence. In this way Oliver unwittingly falls in with an infamous Jewish criminal known as Fagin, the gentleman of whom the Artful Dodger spoke. Ensnared, Oliver lives with Fagin and his gang of juvenile pickpockets in their lair at Saffron Hill for some time, unaware of their criminal occupations. He believes they make wallets and handkerchiefs.
Solution: Who believes Fagin's gang make wallets and handkerchiefs?.
Reason: This question is based on the following sentence in the passage "He believes they make wallets and handkerchiefs". It evaluates the understanding that the pronoun "he" refers to name "Oliver". You can ask questions like this one about most pronouns in a paragraph.

Now, solve this instance: Passage: Since 1718, transportation to the American colonies had been a penalty for various offences in Britain, with approximately one thousand convicts transported per year across the Atlantic. Forced to find an alternative location after the loss of the Thirteen Colonies in 1783, the British government turned to the newly discovered lands of Australia. The coast of Australia had been discovered for Europeans by the Dutch explorer Willem Janszoon in 1606 and was named New Holland by the Dutch East India Company, but there was no attempt to colonise it. In 1770 James Cook discovered the eastern coast of Australia while on a scientific voyage to the South Pacific Ocean, claimed the continent for Britain, and named it New South Wales. In 1778, Joseph Banks, Cook's botanist on the voyage, presented evidence to the government on the suitability of Botany Bay for the establishment of a penal settlement, and in 1787 the first shipment of convicts set sail, arriving in 1788. Britain continued to transport convicts to New South Wales until 1840, to Tasmania until 1853 and to Western Australia until 1868. The Australian colonies became profitable exporters of wool and gold, mainly because of gold rushes in the colony of Victoria, making its capital Melbourne for a time the richest city in the world and the second largest city (after London) in the British Empire.During his voyage, Cook also visited New Zealand, first discovered by Dutch explorer Abel Tasman in 1642, and claimed the North and South islands for the British crown in 1769 and 1770 respectively. Initially, interaction between the indigenous Māori population and Europeans was limited to the trading of goods. European settlement increased through the early decades of the 19th century, with numerous trading stations established, especially in the North. In 1839, the New Zealand Company announced plans to buy large tracts of land and establish colonies in New Zealand. On 6 February 1840, Captain William Hobson and around 40 Maori chiefs signed the Treaty of Waitangi. This treaty is considered by many to be New Zealand's founding document, but differing interpretations of the Maori and English versions of the text have meant that it continues to be a source of dispute.
Student:
What is the last name of the captain that signed the treaty that considered by many to be New Zealand's founding document?
