In this task, you're given a question, along with a context passage which has extra information available on certain terms mentioned in it, i.e., the proper nouns in the passage. Your job is to determine whether information from more than one term is needed to answer the question. Indicate your choice as `a` for Yes or `b` for No.

Example Input: Question: What was the population of the Hejaz region during The Battle of Badr? Passage:The Battle of Badr (), fought on Tuesday, 13 March 624 CE (17 Ramadan, 2 AH in the Islamic calendar) in the Hejaz region of western Arabia (present-day Saudi Arabia), was a key battle in the early days of Islam and a turning point in Muhammad's struggle with his opponents among the Quraish in Mecca. The battle has been passed down in Islamic history as a decisive victory attributable to divine intervention, or by secular sources to the strategic genius of Muhammad. It is one of the few battles specifically mentioned in the Quran. All knowledge of the battle at Badr comes from traditional Islamic accounts, both hadiths and biographies of Muhammad, recorded in written form some time after the battle. There is little evidence outside of these of the battle. There are no descriptions of the battle prior to the 9th century.

Example Input: Question: What is the population of the city where the port the Sibiryakov reached after 65 days is located? Passage:A. Sibiryakov sailed on 28 June 1932 from the Krasny (previously Sobornoy) docks in Arkhangelsk, crossed the Kara Sea and chose a northern, unexplored way around Severnaya Zemlya to the Laptev Sea. In September, after calling at Tiksi and the mouth of the Kolyma, the propeller shaft broke and the icebreaker drifted for 11 days. However, A. Sibiryakov crossed the Chukchi Sea using improvised sails and arrived in the Bering Strait in October. A. Sibiryakov reached the Japanese port of Yokohama after 65 days, having covered more than in the Arctic seas. This was regarded as a heroic feat of Soviet polar seamen and Chief of Expedition Otto Schmidt and Captain Vladimir Voronin were received with many honors at their return to Russia.

Example Input: Question: Who founded Christianity Today? Passage:Jonathan Widran of AllMusic said "It's too early in her career to know whether this powerhouse singer/songwriter will ever reach the heights of Contemporary Christian Music's other Grant, but a bevy of top producers come on board this sparkling debut to launch Natalie Grant towards this goal. All of these studio wizards (Eric Foster White, Tommy Sims, and Michael Lloyd) are better-known for their secular pop music, and the variety of atmospheres they create poise Grant for crossover pop success. It also helps that the lyrics Grant sings are designed as inspirational, rather than preachy. Torchy tracks like 'I Am Not Alone' and rock-driven anthems like 'I Will Be' could definitely lead both teenagers looking for substance, and adult contemporary audiences, to a deeper examination of important spiritual issues. Grant's wide-ranging pipes (yes, think potential diva) would surely sound great without all the production energy, but nearly every up-tempo tune here is an irresistible mix of pop/rock and modern soul flavors. The title track is all thump and hook, and some of the vocal texturing will remind fans of Point of Grace. Another POG-like tune, 'Days Like These', is driven by jangly alternative pop guitars. A few tracks touch on simple exotica, most notably "Love Without Limits" with its swirling flamenco strings. Amidst the playful spirit is Grant's most heartfelt tune, a lush and teary, almost breathless tribute to her father, 'Always Be Your Baby' This tune alone indicates that we're dealing with a major new talent whose deeper life extends from the spiritual into the musical." Christianity Todays Russ Breimeier stated "In a relatively short time Natalie Grant has earned a reputation for three things rather unique to her five-year career. First, she's released every album on a different record label. Both Benson and Pamplin have since closed their doors—'the curse' will likely end with Curb, which is relatively secure under the wings of Warner Brothers' Christian Music Division. Second, the Seattle-born artist is well-known for her protestations about being labeled a 'pop diva'. There is typically a negative connotation to the 'd'-word that flies in the face of Natalie's humble servant attitude and her desire to focus her music on the goodness of God. Unfortunately for her, the diva label is an apt description of her musical styling, which leads into the third unique trait. Despite her diminutive size, Natalie has an impressively big voice with enough nuance to hold her own among any of the classic pop divas (Mariah Carey, Celine Dion, Whitney Houston, take your pick), earning her multiple Dove nominations for Female Vocalist of the Year. Undeterred by collapsing record labels and pop music stereotypes, Natalie admirably presses on with Deeper Life, her third effort, by stretching her own artistic skills. Her previous album, Stronger (released in 2001), featured her first attempts at songwriting by co-writing a handful of tracks. On Deeper Life, she co-writes nearly every song. Additionally, Natalie steps up as co-producer of this album, joining a slew of A-list pop producers and songwriters: Tommy Simms (CeCe Winans, Anointed), Eric Foster White (Jessica Simpson, Whitney Houston), Bryan Lenox (Michael W. Smith, Ronnie Freeman), Bernie Herms (Plus One), and Rob Graves (songwriter and guitarist on Joy Williams's By Surprise). The approach on this project was to create an album that relied less on programmed pop and more on live musicians, and the results are indeed stunning. I daresay this is Natalie's best-sounding album yet. But we must keep it in perspective. This is still R&B-flavored; adult contemporary pop a la Mariah Carey, Jaci Velasquez, Kelly Clarkson, Jessica Simpson, and many others. It is most certainly not (as suggested by the press bio) the classic rock sound of Sheryl Crow or the modern pop/rock of Avril Lavigne. Christian adult contemporary and inspirational pop speaks for itself—some find it meaningful and poignant, while others find it clichéd and boring. In that spirit, the songs of Deeper Life are best explored for what they are—you'll know by the titles, lyrics, and styles if this music matches or offends your tastes. Nevertheless, there's no getting around Natalie's vocal prowess or the superior production, which means you're bound to be impressed with Deeper Life if you enjoy first-rate pop." Heather Marsden of Cross Rhythms claimed "This is Natalie Grant's third album and is positive proof that her new home at Curb Records is working well for her. The album opens with the upbeat title track 'Deeper Life', a poppy feel good song that's easy to pick up and sing along. 'Days Like These' and 'I Will Be' are in a similar style without being repetitions of the first song. The songs 'That's When I Give Up (On Loving You)', 'Live for Today' and 'I Desire' have a more acoustic rock kind of sound—similar to that of Michelle Branch. The bonus track 'No Sign of It' has been featured in the new Gwyneth Paltrow film View from the Top. Deeper Life contains some of Grant's best work, it's a great record with a good message, sure to please her growing number of fans and draw in some new ones." JesusFreakHideout's Shaun Stevenson remarked "Things haven't always been easy for Natalie Grant. After changing record companies twice, Grant has finally found a home with Curb Records. And now, with the release of Deeper Life, Grant is sure headed in the right direction with a solid third album. Albums are always opening with something upbeat these days, and Deeper Life opens things off in the right direction. With plenty of signature Grant sounds, the song really reflects what this album is all about: seeking the deeper life in Jesus Christ. Natalie Grant sure has something going for her. With this newest album, containing some of her strongest work to date, she's really outdone herself. A solid record, a solid message, and a solid musical base, Deeper Life is sure to please fans of Grant's previous work, and it's also sure to bring in new listeners. Trouble has come to Natalie Grant in the past, but now, there's no sign of it, and her skies are definitely clear today."
