Context and question: 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?
Answer: receptor molecules on the membrane of the synapse's target cell
Context and question: Since the start of the 1994–95 season, the FA Cup has been sponsored. However, to protect the identity of the competition, the sponsored name has always included 'The FA Cup' in addition to the sponsor's name, unlike sponsorship deals for the League Cup where the word 'cup' is preceded by only the sponsor's name. Sponsorship deals run for four years, though – as in the case of E.ON – one-year extensions may be agreed. Emirates airline is the sponsor from 2015 to 2018, renaming the competition as 'The Emirates FA Cup', unlike previous editions, which included 'The FA Cup in association with E.ON' and 'The FA Cup with Budweiser'.
Who is the current sponsor? 
Answer: Emirates airline is the sponsor from 2015 to 2018
Context and question: Federalism also finds expression in ecclesiology (the doctrine of the church). For example, presbyterian church governance resembles parliamentary republicanism (a form of political federalism) to a large extent. In Presbyterian denominations, the local church is ruled by elected elders, some of which are ministerial. Each church then sends representatives or commissioners to presbyteries and further to a general assembly. Each greater level of assembly has ruling authority over its constituent members. In this governmental structure, each component has some level of sovereignty over itself. As in political federalism, in presbyterian ecclesiology there is shared sovereignty.
What does each lesser level of assembly have?
Answer:
