Task: Question Answering
Input (English): Background Paragraph: Anemophilous pollen grains are light and non-sticky, so that they can be transported by air currents. They are typically 20–60 micrometres (0.0008–0.0024 in) 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. 
Story: A scientist has just returned to the lab after working out in the field. While in the field, she collected two flowers to examine in detail. She puts the first flower, flower X, under a microscope and begins to look at it. After examination she determines it's an anemophilous plant. She then takes flower Y and repeats the same process to determine that it's an entomophilous type of plant. 
Question: Is flower Y or flower X's pollen smaller?
Output (English): flower X.
