question:
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.

question:
Question: Who was Akbar's predecessor to the Mughal throne? Passage:Gauda was once the "capital of the ancient bhukti or political division of Bengal known as Pundravardhana which lay on the eastern extremity of the Gupta Empire." During the rule of the Sena Dynasty, in the 11th-12th century, Gauda was rebuilt and extended as Lakshmanawati (later Lakhnauti), and it became the hub of the Sena empire. Gauda was conquered by Muhammad bin Bakhtiyar Khalji in 1205. During the Turko-Afghan period, "the city of Lakhnauti or Gauda continued to function initially as their capital but was abandoned in 1342 by the Ilyas Shahi sultans in favour of Pandua because of major disturbances along the river course of the Ganga." "Pandua then lay on the banks of the Mahananda, which was the major waterway of the sultanate at the time. However, when the Mahananda too began to veer away from the site of Pandua in the mid-15th century, Gauda was rebuilt and restored to the status of capital city by the Hussain Shahi sultans"... With the ascent of Akbar to the Mughal throne at Delhi... the Mughals annexed the ancient region of Gauda in 1576 and created the Diwani of Bengal. The centre of regional power shifted across the Ganga to Rajmahal. Following the demise of the independent sultanate, the regional importance of the Gauda or Malda region declined irreversibly and the city of Gauda was eventually abandoned.

question:
Question: How many copies did the single that featured a duet with Monica sell? Passage:In June 1998, Norwood released her second album Never Say Never. Boosted by the success of its number-one lead single "The Boy Is Mine", a duet with singer Monica, it facilitated Norwood in becoming a viable recording artist with media–crossing appeal. In total, the album sold 16 million copies worldwide and spawned seven singles, including Norwood's second number-one song, the Diane Warren-penned "Have You Ever?". Also in 1998, Norwood made her big screen debut in a supporting role in the slasher sequel, I Still Know What You Did Last Summer, which garnered her both a Blockbuster Entertainment Award and an MTV Movie Award nomination for Best Breakthrough Female Performance. The following year, she co-starred with Diana Ross in the telefilm drama Double Platinum about an intense, strained relationship between a mother and daughter. Both Norwood and Ross served as executive producers of the movie which features original songs from Never Say Never and Ross's Every Day Is a New Day (1999).
