Problem: Brain:

Neurotransmitters are chemicals that are released at synapses when an action potential activates them—neurotransmitters attach themselves to receptor molecules on the membrane of the synapse's target cell, and thereby alter the electrical or chemical properties of the receptor molecules. With few exceptions, each neuron in the brain releases the same chemical neurotransmitter, or combination of neurotransmitters, at all the synaptic connections it makes with other neurons; this rule is known as Dale's principle. Thus, a neuron can be characterized by the neurotransmitters that it releases. The great majority of psychoactive drugs exert their effects by altering specific neurotransmitter systems. This applies to drugs such as cannabinoids, nicotine, heroin, cocaine, alcohol, fluoxetine, chlorpromazine, and many others.

What do neurotransmitters attach to?
---
A: receptor molecules on the membrane of the synapse's target cell


Problem: Athanasius of Alexandria:

Throughout most of his career, Athanasius had many detractors. Classical scholar Timothy Barnes relates contemporary allegations against Athanasius: from defiling an altar, to selling Church grain that had been meant to feed the poor for his own personal gain, and even violence and murder to suppress dissent. Athanasius used "Arian" to describe both followers of Arius, and as a derogatory polemical term for Christians who disagreed with his formulation of the Trinity. Athanasius called many of his opponents "Arian", except for Miletus.

What was he accused of doing to a church?
---
A: defiling an altar


Problem: Protestantism:

Episcopalians and Presbyterians, as well as other WASPs, tend to be considerably wealthier and better educated (having graduate and post-graduate degrees per capita) than most other religious groups in United States, and are disproportionately represented in the upper reaches of American business, law and politics, especially the Republican Party. Numbers of the most wealthy and affluent American families as the Vanderbilts and the Astors, Rockefeller, Du Pont, Roosevelt, Forbes, Whitneys, the Morgans and Harrimans are Mainline Protestant families.

Affluent American families are what type of families?
---
A: Mainline Protestant


Problem: Avicenna:

There are occasional brief hints and allusions in his longer works however that Avicenna considered philosophy as the only sensible way to distinguish real prophecy from illusion. He did not state this more clearly because of the political implications of such a theory, if prophecy could be questioned, and also because most of the time he was writing shorter works which concentrated on explaining his theories on philosophy and theology clearly, without digressing to consider epistemological matters which could only be properly considered by other philosophers.

What did Avicenna fear about stating his theories on biology more clearly?
---
A:
unanswerable
