Problem: Predation:

A true predator can commonly be known as one that kills and eats another living thing. Whereas other types of predator all harm their prey in some way, this form kills them. Predators may hunt actively for prey in pursuit predation, or sit and wait for prey to approach within striking distance, as in ambush predators. Some predators kill large prey and dismember or chew it prior to eating it, such as a jaguar or a human; others may eat their (usually much smaller) prey whole, as does a bottlenose dolphin swallowing a fish, or a snake, duck or stork swallowing a frog. Some animals that kill both large and small prey for their size (domestic cats and dogs are prime examples) may do either depending upon the circumstances; either would devour a large insect whole but dismember a rabbit. Some predation entails venom that subdues a prey creature before the predator ingests the prey by killing, which the box jellyfish does, or disabling it, found in the behavior of the cone shell. In some cases, the venom, as in rattlesnakes and some spiders, contributes to the digestion of the prey item even before the predator begins eating. In other cases, the prey organism may die in the mouth or digestive system of the predator. Baleen whales, for example, eat millions of microscopic plankton at once, the prey being broken down well after entering the whale. Seed predation and egg predation are other forms of true predation, as seeds and eggs represent potential organisms. Predators of this classification need not eat prey entirely. For example, some predators cannot digest bones, while others can. Some may eat only part of an organism, as in grazing (see below), but still consistently cause its direct death.

What do prey sometimes consume as food?

A: unanswerable


Problem: Phonology:

The principles of phonological analysis can be applied independently of modality because they are designed to serve as general analytical tools, not language-specific ones. The same principles have been applied to the analysis of sign languages (see Phonemes in sign languages), even though the sub-lexical units are not instantiated as speech sounds.

What are the principles of sign language able to be applied separately from?
---
A: unanswerable


Problem: Frédéric Chopin:

Chopin also endowed popular dance forms with a greater range of melody and expression. Chopin's mazurkas, while originating in the traditional Polish dance (the mazurek), differed from the traditional variety in that they were written for the concert hall rather than the dance hall; "it was Chopin who put the mazurka on the European musical map." The series of seven polonaises published in his lifetime (another nine were published posthumously), beginning with the Op. 26 pair (published 1836), set a new standard for music in the form. His waltzes were also written specifically for the salon recital rather than the ballroom and are frequently at rather faster tempos than their dance-floor equivalents.

Chopin was credited for making what more internationally known?
---
A: mazurkas


Problem: New Haven, Connecticut:

On July 5, 1779, 2,600 loyalists and British regulars under General William Tryon, governor of New York, landed in New Haven Harbor and raided the 3,500-person town. A militia of Yale students had been prepping for battle, and former Yale president and Yale Divinity School professor Naphtali Daggett rode out to confront the Redcoats. Yale president Ezra Stiles recounted in his diary that while he moved furniture in anticipation of battle, he still couldn't quite believe the revolution had begun. New Haven was not torched as the invaders did with Danbury in 1777, or Fairfield and Norwalk a week after the New Haven raid, so many of the town's colonial features were preserved.

After the battle were New Haven historical features lost or torched?
---
A:
town's colonial features were preserved.
