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.

[Q]: Passage: Sitting in deckchairs and touring churches is not the holiday 17-year-old Richard wants, but his parents insist on taking him. They are staying at the Tregarron guesthouse in the (fictional) seaside town of Easton in Suffolk. This traditional English boarding house is owned and run by the formidable  Miss Wilbraham.   
On arrival, Richard befriends Edwin, who is girl-crazy and takes Richard under his wing. In search of girls, Richard and Edwin attend a beach service organized by the local church  youth group. After the type of evening one might expect at such a gathering, they enjoy a brief tryst with the twin daughters of the minister. 
The following evening another visitor, Julia, agrees to a date with Edwin but only on condition that Anna, her Dutch foreign exchange student friend, can join them. Edwin persuades Richard to join them to make up a foursome. Escaping from his parents on the pretence that the quartet is heading to the youth group's Sausage Sizzle, Richard and his friends visit a local jazz club instead. 
Anna attempts to sneak away with some local bikers and Richard gives chase. As Anna rides away on the back of one biker's machine, Richard jumps on the other. The bikes race off into the sand dunes; where Richard and Anna fall off the pillions and into each other's arms. Richard is annoyed but Anna finds the whole affair amusing. Reaching for a handkerchief to clean a cut on his head, Richard also pulls out a condom that he has taken from Edwin's room.
Julia and Edwin, meanwhile, have been to fetch help. Julia's father, Richard's parents and the minister from the youth group set off to rescue Richard and Anna. A lady walking her dog along the beach stumbles across Richard and Anna as it becomes clear that Richard has experienced sexual initiation. The parents and the minister round the corner just in time to catch the teenagers in flagrante delicto.
Both families make excuses to end their holidays early and head for home.
[A]: What are the first names of the foursome that are going out together?


[Q]: Passage: All whales are carnivorous and predatory. Odontocetes, as a whole, mostly feed on fish and cephalopods, and then followed by crustaceans and bivalves. All species are generalist and opportunistic feeders. Mysticetes, as a whole, mostly feed on krill and plankton, followed by crustaceans and other invertebrates. A few are specialists. Examples include the blue whale, which eats almost exclusively krill, the minke whale, which eats mainly schooling fish, the sperm whale, which specialize on squid, and the grey whale which feed on bottom-dwelling invertebrates. The elaborate baleen "teeth" of filter-feeding species, mysticetes, allow them to remove water before they swallow their planktonic food by using the teeth as a sieve. Usually whales hunt solitarily, but they do sometimes hunt cooperatively in small groups. The former behaviour is typical when hunting non-schooling fish, slow-moving or immobile invertebrates or endothermic prey. When large amounts of prey are available, whales such as certain mysticetes hunt cooperatively in small groups. Some cetaceans may forage with other kinds of animals, such as other species of whales or certain species of pinnipeds.Large whales, such as mysticetes, are not usually subject to predation, but smaller whales, such as monodontids or ziphiids, are. These species are preyed on by the killer whale or orca. To subdue and kill whales, orcas continuously ram them with their heads; this can sometimes kill bowhead whales, or severely injure them. Other times they corral the narwhals or belugas before striking. They are typically hunted by groups of 10 or fewer orcas, but they are seldom attacked by an individual. Calves are more commonly taken by orcas, but adults can be targeted as well.These small whales are also targeted by terrestrial and pagophilic predators. The polar bear is well adapted for hunting Arctic whales and calves. Bears are known to use sit-and-wait tactics as well as active stalking and pursuit of prey on ice or water. Whales lessen the chance of predation by gathering in groups. This however means less room around the breathing hole as the ice slowly closes the gap. When out at sea, whales dive out of the reach of surface-hunting orcas. Polar bear attacks on belugas and narwhals are usually successful in winter, but rarely inflict any damage in summer.
[A]: What is the overarching name of the broader species that all are generalist and opportunistic feeders?


[Q]: Passage: "Smells Like Teen Spirit" was first performed live on April 17, 1991 at the OK Hotel in Seattle, Washington. The performance is featured on the DVD of the 2004 box set With the Lights Out, while shorter clips are included on the Nevermind Classic Albums DVD, as well as the documentary film Hype! As the song's lyrics had not yet been entirely written, there are notable differences between it and the final version. For example, the first performance started with "Come out and play, make up the rules" instead of the eventual opening of "Load up on guns, bring your friends". A recording of the earlier version appears on With the Lights Out and again on Sliver: The Best of the Box. A similar early live performance of the song is found in the documentary 1991: The Year Punk Broke, filmed during a 1991 summer tour in Europe with Sonic Youth.
Nirvana often altered the song's lyrics and tempo for live performances. Some live performances of the song had the line "our little group has always been" changed to "our little tribe has always been", which can be heard on the 1996 live album From the Muddy Banks of the Wishkah. Rolling Stone remarked that the Wishkah version of "Teen Spirit" "[found] Cobain's guitar reeling outside the song's melodic boundaries and sparking new life in that nearly played-out hit". A notable alternate performance of "Smells Like Teen Spirit" occurred on BBC's Top of the Pops in 1991, during which the band refused to mime to the pre-recorded backing track and Cobain sang in a deliberately low voice and altered numerous lyrics in the song (for example, "Load up on guns, bring your friends" became "Load up on drugs, kill your friends").   Cobain later said he was trying to sound like former Smiths frontman Morrissey. When Top of the Pops was cancelled in 2006, The Observer listed Nirvana's performance of "Smells Like Teen Spirit" as the third greatest in the show's history. This performance can be found on the 1994 home video Live! Tonight! Sold Out!!.
