Question: Emotions are thought to be related to certain activities in brain areas that direct our attention, motivate our behavior, and determine the significance of what is going on around us. Pioneering work by Broca (1878), Papez (1937), and MacLean (1952) suggested that emotion is related to a group of structures in the center of the brain called the limbic system, which includes the hypothalamus, cingulate cortex, hippocampi, and other structures. More recent research has shown that some of these limbic structures are not as directly related to emotion as others are while some non-limbic structures have been found to be of greater emotional relevance.
Try to answer this question if possible: Along with the cingulate cortex and hippocampi, what structure is not a notable part of the limbic system?
Answer: unanswerable
Question: Electrocution was the preferred method of execution during the 20th century. Electric chairs have commonly been nicknamed Old Sparky; however, Alabama's electric chair became known as the "Yellow Mama" due to its unique color. Some, particularly in Florida, were noted for malfunctions, which caused discussion of their cruelty and resulted in a shift to lethal injection as the preferred method of execution. Although lethal injection dominates as a method of execution, some states allow prisoners on death row to choose the method used to execute them.
Try to answer this question if possible: What was an uncommon nickname for the electric chair?
Answer: unanswerable
Question: Although asthma is a chronic obstructive condition, it is not considered as a part of chronic obstructive pulmonary disease as this term refers specifically to combinations of disease that are irreversible such as bronchiectasis, chronic bronchitis, and emphysema. Unlike these diseases, the airway obstruction in asthma is usually reversible; however, if left untreated, the chronic inflammation from asthma can lead the lungs to become irreversibly obstructed due to airway remodeling. In contrast to emphysema, asthma affects the bronchi, not the alveoli.
Try to answer this question if possible: What diseases are examples of airway remodeling?
Answer: unanswerable
Question: In the last years of the nineteenth century, Planck was investigating the problem of black-body radiation first posed by Kirchhoff some forty years earlier. It is well known that hot objects glow, and that hotter objects glow brighter than cooler ones. The electromagnetic field obeys laws of motion similarly to a mass on a spring, and can come to thermal equilibrium with hot atoms. The hot object in equilibrium with light absorbs just as much light as it emits. If the object is black, meaning it absorbs all the light that hits it, then its thermal light emission is maximized.
Try to answer this question if possible: What is known about the light absorption of a hot object in equilibrium with light?
Answer:
absorbs just as much light as it emits
