Answer:
Jessica should consume more of good A.
Explanation:
Jessica spends all her income on two goods, A and B.
The price of A is $5, and the price of B is $7.
At the current consumption bundle, the marginal utility of A is 10, and the marginal utility of B is 21.
The total utility is maximized when the ratio of marginal utility and price of the goods consumed is equal for all the goods in the bundle.
The ratio for Good A
= 
= 2
The ratio for good B
= 
= 3
Since the ratio is higher for good B, the consumer should shift from consumption of good B to good A until the ratio is equal for both the goods.

Answer: cold and warm air masses interact in an unstable environment.
Explanation: Extratropical cyclones, sometimes called mid-latitude cyclones or wave cyclones, are low-pressure areas which, along with the anticyclones of high-pressure areas, drive the weather over much of the Earth. Extratropical cyclones are capable of producing anything from cloudiness and mild showers to heavy gales, thunderstorms, blizzards, and tornadoes. These types of cyclones are defined as large scale (synoptic) low pressure weather systems that occur in the middle latitudes of the Earth. In contrast with tropical cyclones, extratropical cyclones produce rapid changes in temperature and dew point along broad lines, called weather fronts, about the center of the cyclone .According to the polar-front theory, extratropical cyclones develop when a wave forms on a frontal surface separating a warm air mass from a cold air mass. As the amplitude of the wave increases, the pressure at the centre of disturbance falls, eventually intensifying to the point at which a cyclonic circulation begins. The decay of such a system results when the cold air from the north in the Northern Hemisphere, or from the south in the Southern Hemisphere, on the western side of such a cyclone sweeps under all of the warm tropical air of the system so that the entire cyclone is composed of the cold air mass. This action is known as occlusion.Extratropical cyclones arise through a process called cyclogenesis, in which cold and warm air masses interact in an unstable environment.
Answer:
Steve Jobs coming back, Innovations, and Tim Cook taking over as COO
Explanation:
The fluctuations in stock prices of a company are due to improved performance of the company in meeting it's objectives and perception that the business will do better in the future.
In the given scenario there was an initial increase in Apple’s stock price from $27.97 to $702.10, an increase of 25 times.
This can be attributed to the return of Steve Jobs as the CEO of Apple. There was a confidence boost by his coming back. Also there were various innovations like: iPhone, iMac, iPod, and iTunes. These improved the performance and by extension share price of Apple.
However when Tim Cook took over as COO he reduced production by half resulting in stock price decrease by 37% from its peak in September 2012 until the end of March 2013, from $702.10 to $442.66.
John Maynard Keynes believed in government intervention into the economy to regulate the markets. Therefore, this statement would signify Keynes' view that B) government regulation is necessary to stabilize the economy.
