Passage: In pre-contact times, natives traveling up Mauna Kea were probably guided more by landscape than by existing trails, as no evidence of trails has been found. It is possible that natural ridges and water sources were followed instead. Individuals likely took trips up Mauna Kea's slopes to visit family-maintained shrines near its summit, and traditions related to ascending the mountain exist to this day. However, very few natives reached the summit, because of the strict kapu placed on it.In the early 19th century, the earliest notable recorded ascents of Mauna Kea included the following:
On August 26, 1823, Joseph F. Goodrich, an American missionary, made the first recorded ascent in a single day; however, a small arrangement of stones he observed suggested he was not the first human on the summit. He recorded four ecosystems as he travelled from base to summit, and also visited Lake Waiau.
On June 17, 1825, an expedition from HMS Blonde, led by botanist James Macrae, reached the summit of Mauna Kea. Macrae was the first person to record the Mauna Kea silversword (Argyroxiphium sandwicense), saying: "The last mile was destitute of vegetation except one plant of the Sygenisia tribe, in growth much like a Yucca, with sharp pointed silver coloured leaves and green upright spike of three or four feet producing pendulous branches with brown flowers, truly superb, and almost worth the journey of coming here to see it on purpose."
In January 1834, David Douglas climbed the mountain and described extensively the division of plant species by altitude. On a second climb in July, he was found dead in a pit intended to catch wild cattle. Although murder was suspected, it was probably an accidental fall. The site, Ka lua kauka  19°53′17″N 155°20′17″W, is marked by the Douglas fir trees named for him.
In 1881, Queen Emma traveled to the peak to bathe in the waters of Lake Waiau during competition for the role of ruling chief of the Kingdom of Hawaii.
On August 6, 1889, E.D. Baldwin left Hilo and followed cattle trails to the summit.In the late 19th and early 20th centuries trails were formed, often by the movement of game herds, that could be traveled on horseback. However, vehicular access to the summit was practically impossible until the construction of a road in 1964, and it continues to be restricted. Today, multiple trails to the summit exist, in various states of use. 
Question: What is the full name of the person who was found dead in a pit intended to catch wild cattle?
David Douglas.

Passage: Roy DuBro and Ed Klingbottom are garbage men who are constantly undermined by their corrupt boss Junior Assistant Dispatcher Trainee Stanley Snyder.
One day, the earth is secretly invaded by an army of flying saucers, commanded by a Darth Vader-esque alien called Glaxxon. A saucer abducts the two men and the aliens on board attempt to vivisect them. They awaken just in time and escape back to earth with an alien fire extinguisher. When they arrive late for work and try to tell Stanley about the aliens, he doesn't believe them, having heard every alien story ever from fellow worker Old Bob.
President Smith and his significantly more competent press secretary receive news about the invasion from General Vice and the President tells his advisor, Dr. Strangemeister, to find two people with alien experience and make them into secret agents. Unbeknownst to anyone, Strangemeister is secretly in league with Glaxon, who is infuriated by Ed and Roy's interference. Strangemeister hires the two of them, believing that they are destined to fail and transforms them into 'The Men in White'.
The aliens start abducting people all over the world. Roy suggests the two of them use a cow as bait. The plan works and they successfully capture an alien spaceship. They discover  a device that makes them forget the last several seconds, and the two of them get stuck in a continuous loop for several hours until its batteries run down. 
Question: Who hires the garbage men who work for a corrupt boss as secret agents??
Dr. Strangemeister.

Passage: After a textual montage summarizing Edgar Allan Poe's life, the film begins in late September 1849 with Poe awakening from a hallucination where he is buried alive.  He prepares to take a trip to New York City via a ferry steamboat from Richmond, Virginia, to Baltimore, and from there, another ferry to New York City itself.  He discusses his plans to marry his childhood sweetheart Sarah Elmira Royster with a stranger taking the same steamboat, who suggests that he meet with a few potential investors for his planned magazine The Stylus.  Though Poe had intended only to pass through Baltimore, he agrees to meet the investors who, one by one, turn down his request for funding. 
Poe is depicted as having some type of memory loss, which is first evident when he offers to pay his boat fare twice after forgetting he had already paid. In Baltimore, he more than once forgets the arrangements he has made at his hotel as his stay in the city is extended.  One night, he chooses to dine in a local tavern rather than at the hotel.  There, he meets an old friend from his days at West Point.  In desperation, he asks his former classmate and the classmate's companion for money to help start a magazine, saying proudly he has already raised $1,000.  Poe leaves the tavern to retrieve his prospectus for the magazine.  His classmate follows him and beats him up to steal the $1,000 he had collected.
An injured and delirious Poe is then found by organizers of a cooping ring.  The author, along with several others, are forced to multiple polling locations around Baltimore to place multiple votes for the candidate for mayor.  A couple of victims of the scam die amidst the brutality of their captors. 
Question: What is the last name of the person who discusses his plans to marry his childhood sweetheart?

Poe.
