The correct options are as follows:
1. DECREASE / INDETERMINATE.
We are told in the question that cafeteria meals are inferior goods. An inferior good is a type of good whose demand decreases as the income of the consumer increases. That is, when the income of a consumer increases, such consumer will buy less of inferior goods and instead move on to buy goods that are more expensive. Thus, the demand for an inferior good will decrease as the income of the consumer increases. People usually buy inferior goods when they have low incomes, immediately their income increases, they move on to buy more expensive goods. Examples of inferior goods are: cheap cars, cheap frozen foods, intercity bus services, etc.
2. I, II AND III
Aggregate demand refers to the total demand for goods and services in a particular economy at a given point in time. The factors that affect aggregate demand include: consumers' expenditures, investment spending on capital goods, government spending and foreign goods. Shifts in these factors will either increase or decrease the aggregate demand. The following factors increase the aggregate demand: When the government reduces the income taxes paid by workers, increases in excess capacity and increase in quantity of foreign goods demanded.
3. AN INCREASE IN EXPORT.
An increase in the amount of goods exported by a country will lead to an increase in the amount of foreign incomes earn by the country, this in turn will increase the spending capacity of that country. Thus, increase in foreign incomes earn by an economy leads to increase in aggregate demand.
The Presiding Officer of the United States Senate is the person who presides over the United States Senate and is charged with maintaining order and decorum, recognizing members to speak, and interpreting the Senate's rules, practices, and precedents. Senate presiding officer is a role, not an actual office. The actual role is usually performed by one of three officials: the Vice President; an elected United States Senator; or, in special cases, the Chief Justice. Outside the constitutionally mandated roles, the actual appointment of a person to do the job of presiding over the Senate as a body is governed by Rule I of the Standing Rules.
The Vice President is assigned the responsibility by the Constitution of presiding over the Senate and designated as its president. The vice president has the authority (ex office, for they are not an elected member of the Senate) to cast a tie-breaking vote. Early vice presidents took an active role in regularly presiding over proceedings of the body, with the president pro tempore only being called on during the vice president's absence. During the 20th century, the role of the vice president evolved into more of an executive branch position. Now, the vice president is usually seen as an integral part of a president's administration and presides over the Senate only on ceremonial occasions or when a tie-breaking vote may be needed.[1]
The Constitution also provides for the appointment of one of the elected senators to serve as President pro tempore. This senator presides when the vice president is absent from the body. The president pro tempore is selected by the body specifically for the role of presiding in the absence of (as the meaning of pro tempore, literally "for the time being") the actual presiding officer. By tradition, the title of President pro tempore has come to be given more-or-less automatically to the most senior senator of the majority party. In actual practice in the modern Senate, the president pro tempore also does not often serve in the role (though it is their constitutional right to do so). Instead, as governed by Rule I, they frequently designate a junior senator to perform the function.
When the Senate hears an impeachment trial of the President of the United States, by the procedure established in the Constitution, the Chief Justice is designated as the presiding officer.
