Input: The highest point of a wave is the crest. The lowest point is the trough. The vertical distance between a crest and a trough is the height of the wave. Wave height is also called amplitude. The horizontal distance between two crests is the wavelength. Both amplitude and wavelength are measures of wave size. The size of an ocean wave depends on how fast, over how great a distance, and how long the wind blows. The greater each of these factors is, the bigger a wave will be. Some of the biggest waves occur with hurricanes. A hurricane is a storm that forms over the ocean. Its winds may blow more than 150 miles per hour! The winds also travel over long distances and may last for many days.
"How many times is wind mentioned?" is "1"?

OPTIONS:
- no

Input: Relying on an animal to come by is risky. A flower may have to wait a long time for the right animals to come by. What if one never passes close enough to the flower? Hoping the wind will blow is also risky for a plant. What if the wind does not blow? What if the blowing pollen does not land on another flower? The wind could even blow the pollen over the ocean where it is wasted. Giving free nectar is costly. It is not a good use of the plants energy. A plant uses a lot of energy to produce nectar. Some animals may just drink the nectar. They may not carry off any pollen in return. To improve their chances, plants evolved special traits. For example, they developed ways to hide their nectar. Only certain animals were able to get at the plants hidden nectar. These specific animals might be more likely to visit only flowers of the same species. This was also a benefit for some animals. Animals also evolved special traits to get to the nectar.
"How do animals pose a threat to pollination?" is "Drink nectar without transferring pollen"?

OPTIONS:
- no
- yes
Output: yes
Input: Charlie Mershone had no difficulty in securing his release when Parker came on duty at six o'clock. He called up a cab and went at once to his rooms at the Bruxtelle; and Fogerty followed him. While he discarded his dress-coat, took a bath and donned his walking suit Mershone was in a brown study. Hours ago Louise had been safely landed at the East Orange house and placed in the care of old Madame Cerise, who would guard her like an ogre. There was no immediate need of his hastening after her, and his arrest and the discovery of half his plot had seriously disturbed him. This young man was no novice in intrigue, nor even in crime. Arguing from his own stand-point he realized that the friends of Louise were by this time using every endeavor to locate her. They would not succeed in this, he was positive. His plot had been so audacious and all clews so cleverly destroyed or covered up that the most skillful detective, knowing he had abducted the girl; would be completely baffled in an attempt to find her.
"Were Louise and Charlie in the same place?" is "He is at the Bruxtelle"?
