Q: Many types of nuclear propulsion have been proposed, and some of them (e.g. NERVA) tested for spacecraft applications.
Can we conclude that can we use nuclear power to propel spaceships?
A: yes

Q: The structures of the limbic system are involved in motivation, emotion, learning, and memory. The limbic system is where the subcortical structures meet the cerebral cortex. The limbic system operates by influencing the endocrine system and the autonomic nervous system. It is highly interconnected with the nucleus accumbens, which plays a role in sexual arousal and the ''high'' derived from certain recreational drugs. These responses are heavily modulated by dopaminergic projections from the limbic system. In 1954, Olds and Milner found that rats with metal electrodes implanted into their nucleus accumbens, as well as their septal nuclei, repeatedly pressed a lever activating this region, and did so in preference to eating and drinking, eventually dying of exhaustion. The limbic system also includes the basal ganglia. The basal ganglia are a set of subcortical structures that direct intentional movements. The basal ganglia are located near the thalamus and hypothalamus. They receive input from the cerebral cortex, which sends outputs to the motor centers in the brain stem. A part of the basal ganglia called the striatum controls posture and movement. Recent studies indicate that, if there is an inadequate supply of dopamine, the striatum is affected, which can lead to visible behavioral symptoms of Parkinson's disease.
Can we conclude that is the limbic system part of the cerebral cortex?
A: no

Q: Scallops are characterized by offering two flavors and textures in one shell: the meat, called ''scallop'', which is firm and white, and the roe, called ''coral'', which is soft and often brightly coloured reddish-orange. Sometimes, markets sell scallops already prepared in the shell, with only the meat remaining. Outside the U.S., the scallop is often sold whole. In the UK and Australia, they are available both with and without coral.
Can we conclude that is the orange bit of a scallop edible?
A: yes

Q: Prior to establishing the nation's capital in Washington, D.C., the United States Congress and its predecessors had met in Philadelphia (Independence Hall and Congress Hall), New York City (Federal Hall), and a number of other locations (York, Pennsylvania; Lancaster, Pennsylvania; Maryland State House in Annapolis, Maryland; and Nassau Hall in Princeton, New Jersey). In September 1774, the First Continental Congress brought together delegates from the colonies in Philadelphia, followed by the Second Continental Congress, which met from May 1775 to March 1781.
Can we conclude that was nyc ever the capital of the us?
A:
yes
