In this task, you're expected to write answers to questions involving multiple references to the same entity. The answer to the question should be unambiguous and a phrase in the paragraph. Most questions can have only one correct answer.

[EX Q]: Passage: After their HIV positive mother's death, Derick and Margaret collect wood and construct a human-length box with wheels. Then, they journey with it from Kampala to Kasangombe in a heartbreaking bid to overcome poverty and experience hope. The journey throws them dangerous experiences on unpredictable Ugandan roads. Their mother's dying wish had set them off on a seemingly impossible journey to find a relative they do not even know.
Before her death, she leaves them an envelope addressed to her sister (their auntie) who is married to a hard-working man living in a distant village called Kasangombe with their kids. Ingeniously, Derick creates a coffin using wood he collected from a rubbish dump and adds luggage bag rollers brought by Margaret. On their journey from Kampala City to their aunt's place, they are offered a lift by a seemingly kind man (played by Joel Okuyo Atiku) in a truck who is amazed by their "box". He introduces them to a kid he had taken under his wings relaxing at the back and shows them a photo of a house they can possess if they work for him. At night though, Margaret sees a scary dream where their helper is not exactly as kind as he seemed so she runs out of the truck. Derick follows and the boy throws out their coffin before waving. They walk the rest of the distance.
Initially, their uncle (played by Isaac Muwawu) did not want them in his house because he thought they were HIV-infected. Derick overheard him quarrel with his aunt at night and shook Margaret in the morning from another dream (this time beautiful, where both siblings were smiling and enjoying a picnic in a glorious garden with their aunt, uncle, cousins, dead parents and some whites). Derick convinced her to walk away from the home with him but without a reason. 
Question: How do the pair of siblings finish the last leg of their journey?
[EX A]: They walk.

[EX Q]: Passage: With their love of the Beach Boys and late 1960s bubblegum pop, the Ramones paved the way to what became known as pop punk. In the late 1970s, UK bands such as Buzzcocks and the Undertones combined pop-style tunes and lyrical themes with punk's speed and chaotic edge. In the early 1980s, some of the leading bands in Southern California's hardcore punk rock scene emphasized a more melodic approach than was typical of their peers. According to music journalist Ben Myers, Bad Religion "layered their pissed off, politicized sound with the smoothest of harmonies"; Descendents "wrote almost surfy, Beach Boys-inspired songs about girls and food and being young(ish)". Epitaph Records, founded by Brett Gurewitz of Bad Religion, was the base for many future pop punk bands. Bands that fused punk with light-hearted pop melodies, such as the Queers and Screeching Weasel, began appearing around the country, in turn influencing bands like Green Day and the Offspring, who brought pop punk wide popularity and major record sales. Bands such as the Vandals and Guttermouth developed a style blending pop melodies with humorous and offensive lyrics. Eventually, the geographically large Midwest U.S. punk scene, anchored largely in places like Chicago and Minneapolis, would spawn bands like Dillinger Four who would take a catchy, hooky pop-punk approach and reinfuse it with some of punk's earlier grit and fury, creating a distinctive punk rock sound with a regional tag. This particular substrate still maintains an identity today. The mainstream pop punk of latter-day bands such as Blink-182 is criticized by many punk rock devotees; in critic Christine Di Bella's words, "It's punk taken to its most accessible point, a point where it barely reflects its lineage at all, except in the three-chord song structures.". 
Question: What bands were inspirations to the pop punk bands that achieved wide popularity?
[EX A]: the Queers.

[EX Q]: Passage: The French colonization of Texas began with the establishment of a fort in present-day southeastern Texas. It was established in 1685 near Arenosa Creek and Matagorda Bay by explorer Robert Cavelier de La Salle. He intended to found the colony at the mouth of the Mississippi River, but inaccurate maps and navigational errors caused his ships to anchor instead 400 miles (640 km) to the west, off the coast of Texas. The colony survived until 1688. The present-day town of Inez is near the fort's site.
The colony faced numerous difficulties during its brief existence, including Native American raids, epidemics, and harsh conditions. From that base, La Salle led several expeditions to find the Mississippi River. These did not succeed, but La Salle did explore much of the Rio Grande and parts of east Texas. During one of his absences in 1686, the colony's last ship was wrecked, leaving the colonists unable to obtain resources from the French colonies of the Caribbean. As conditions deteriorated, La Salle realized the colony could survive only with help from the French settlements in Illinois Country to the north, along the Mississippi and Illinois Rivers. His last expedition ended along the Brazos River in early 1687, when La Salle and five of his men were murdered during a mutiny.
Although a handful of men reached Illinois Country, help never made it to the fort. Most of the remaining members of the colony were killed during a Karankawa raid in late 1688, four children survived after being adopted as captives. Although the colony lasted only three years, it established France's claim to possession of the region that is now Texas. The United States later claimed, unsuccessfully, this region as part of the Louisiana Purchase because of the early French colony.
Spain learned of La Salle's mission in 1686. Concerned that the French colony could threaten Spain's control over the Viceroyalty of New Spain and the unsettled southeastern region of North America, the Crown funded multiple expeditions to locate and eliminate the settlement. The unsuccessful expeditions helped Spain to better understand the geography of the Gulf Coast region. When the Spanish finally discovered the remains of the French colony at the fort in 1689, they buried the cannons and burned the buildings. Years later, Spanish authorities built a presidio at the same location. When the presidio was abandoned, the site of the French settlement was lost to history.
The fort was rediscovered by historians and excavated in 1996, and the area is now an archaeological site. In 1995, researchers located the ship La Belle in Matagorda Bay, with several sections of the hull remaining virtually intact. They constructed a cofferdam, the first to be used in North America to excavate the ship as if in dry conditions. In 2000, excavations revealed three of the original structures of the fort, as well as three graves of Frenchmen. 
Question: What is the first name of the person who led several expeditions to find the Mississippi River?
[EX A]:
Robert.
