In this task, you are given a question and a context passage. You have to answer the question based on the given passage.

Ex Input:
neurons talk each other through, Context: The brain is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals. Only a few invertebrates such as sponges, jellyfish, adult sea squirts and starfish do not have a brain; diffuse or localised nerve nets are present instead. The brain is located in the head, usually close to the primary sensory organs for such senses as vision, hearing, balance, taste, and smell. The brain is the most complex organ in a vertebrate's body. In a typical human, the cerebral cortex (the largest part) is estimated to contain 15–33 billion neurons, each connected by synapses to several thousand other neurons. These neurons communicate with one another by means of long protoplasmic fibers called axons, which carry trains of signal pulses called action potentials to distant parts of the brain or body targeting specific recipient cells.

Ex Output:
axons


Ex Input:
How do Presbyterians demonstrate their faith with actions as opposed to words?, Context: Presbyterians place great importance upon education and lifelong learning. Continuous study of the scriptures, theological writings, and understanding and interpretation of church doctrine are embodied in several statements of faith and catechisms formally adopted by various branches of the church, often referred to as "subordinate standards". It is generally considered that the point of such learning is to enable one to put one's faith into practice; some Presbyterians generally exhibit their faith in action as well as words, by generosity, hospitality, as well as proclaiming the gospel of Christ.

Ex Output:
generosity, hospitality


Ex Input:
Who wanted Kip to play himself?, Context: In June 2006, Steven Spielberg announced he would direct a scientifically accurate film about "a group of explorers who travel through a worm hole and into another dimension", from a treatment by Kip Thorne and producer Lynda Obst. In January 2007, screenwriter Jonathan Nolan met with them to discuss adapting Obst and Thorne's treatment into a narrative screenplay. The screenwriter suggested the addition of a "time element" to the treatment's basic idea, which was welcomed by Obst and Thorne. In March of that year, Paramount hired Nolan, as well as scientists from Caltech, forming a workshop to adapt the treatment under the title Interstellar. The following July, Kip Thorne said there was a push by people for him to portray himself in the film. Spielberg later abandoned Interstellar, which was eventually directed by Christopher Nolan.

Ex Output:

people
