In this task, you're given a question, along with a context passage. The passage will not have a direct answer to the question, but can include some information and a clue for the answer. Assuming you can only obtain information about one entity in the passage, your job is to determine whether information from the passage can be used to answer the question. Indicate your choice as `a` for Yes or `b` for No.

Input: Consider Input: Question: What is the scientific name for studying why there are foreign materials in a bee's honey? Passage:Anemophilous pollen grains are light and non-sticky, so that they can be transported by air currents. They are typically in diameter, although the pollen grains of Pinus species can be much larger and much less dense. Anemophilous plants possess well-exposed stamens so that the pollens are exposed to wind currents and also have large and feathery stigma to easily trap airborne pollen grains. Pollen from anemophilous plants tends to be smaller and lighter than pollen from entomophilous ones, with very low nutritional value to insects. However, insects sometimes gather pollen from staminate anemophilous flowers at times when higher-protein pollens from entomophilous flowers are scarce. Anemophilous pollens may also be inadvertently captured by bees' electrostatic field. This may explain why, though bees are not observed to visit ragweed flowers, its pollen is often found in honey made during the ragweed floral bloom. Other flowers that are generally anemophilous are observed to be actively worked by bees, with solitary bees often visiting grass flowers, and the larger honeybees and bumblebees frequently gathering pollen from corn tassels and other grains.

Input: Consider Input: Question: What was the population of Norwood the year that Ken Livingstone got elected to represent it? Passage:Born in Lambeth, South London, to a working-class family, Livingstone joined Labour in 1968 and was elected to represent Norwood at the GLC in 1973, Hackney North and Stoke Newington in 1977, and Paddington in 1981. That year, Labour representatives on the GLC elected him as the council's leader. Attempting to reduce London Underground fares, his plans were challenged in court and declared unlawful; more successful were his schemes to benefit women and underprivileged minorities, despite stiff opposition. The mainstream media gave him the moniker "Red Ken" in reference to his socialist beliefs and heavily criticised him for supporting controversial issues like republicanism, LGBT rights, and a United Ireland. Livingstone was a vocal opponent of the Conservative Party government of Prime Minister Margaret Thatcher, which in 1986 abolished the GLC. Elected as MP for Brent East in 1987, he became closely associated with anti-racist campaigns. He unsuccessfully stood for Labour Party leader on a leftist platform in 1992 and 1994, in the latter losing to Tony Blair. Livingstone became a vocal critic of Blair's New Labour project that pushed the party closer to the centre and won the 1997 general election.

Input: Consider Input: Question: At the time of his death, how old was the artist that Terrell spend nearly two years as a member of their revue? Passage:Terrell's career began as a teenager, first recording for Scepter/Wand Records, before spending nearly two years as a member of James Brown's Revue, recording for Brown's Try Me label. After a period attending college, Terrell recorded briefly for Checker Records, before signing with Motown in 1965. With Gaye, Terrell scored seven Top 40 singles on the Billboard Hot 100, including "Ain't No Mountain High Enough" which was inducted into the Grammy Hall of Fame in 1999, "Ain't Nothing Like the Real Thing" and "You're All I Need to Get By". Terrell's career was interrupted when she collapsed into Gaye's arms as the two performed at a concert at Hampden–Sydney College on October 14, 1967, with Terrell later being diagnosed with a brain tumor. She had eight unsuccessful surgeries before succumbing to the illness on March 16, 1970 at the age of 24.
