Student A:Macroeconomics (from the Greek prefix makro-meaning "large" and economics) is a branch of economics dealing with the performance, structure, behavior, and decision-making of an economy as a whole. This includes national, regional, and global economies. Macroeconomics and microeconomics, a pair of terms coined by Ragnar Frisch, are the two most general fields in economics. In contrast to macroeconomics, microeconomics is the branch of economics that studies the behavior of individuals and firms in making decisions and the interactions among these individuals and firms in narrowly-defined markets.

Answer this question based on the passage: who gave concept of micro and macro economics?
Student B:OK... To answer the above question, the relevant sentence is: Macroeconomics and microeconomics, a pair of terms coined by Ragnar Frisch, are the two most general fields in economics.

Problem:Context: In law, a minor is a person under a certain age, usually the age of majority, which legally demarcates childhood from adulthood. The age of majority depends upon jurisdiction and application, but it is generally 18. Minor may also be used in contexts that are unconnected to the overall age of majority. For example, the drinking age in the United States is usually 21, and younger people are sometimes called minors in the context of alcohol law, even if they are at least 18. The term underage often refers to those under the age of majority, but it may also refer to persons under a certain age limit, such as the drinking age, smoking age, age of consent, marriageable age, driving age, voting age, etc. Such age limits are often different from the age of majority.

Question: when is a child no longer considered a minor?
Solution:OK... To answer this question, we should know that: The age of majority depends upon jurisdiction and application, but it is generally 18.
generally 18.

Student A:David Cassidy recorded an extended live version for his 1974 album Cassidy Live! (Bell Records, UK # 9; recorded live in Great Britain in May 1974). The track features extensive and complex lead-guitar solos by Cassidy himself. The album received rave reviews. Critic Dave Thompson wrote for Allmusic, "Recorded live on his 1974 world tour, at the height (and, though nobody knew it, in the final days) of Cassidy-mania, Cassidy Live is a peculiar document, on the one hand standing as an indication of just how fierce the hysteria around the lad was, but, on the other, living proof of what a sensational showman he was; as evidenced by tracks like' For What It's Worth'." He concluded, "Rock history has sidelined Cassidy with a finality that seems almost personal, shovelling him up a teen idol side street from which the only escape was retirement and resignation. Cassidy Live, however, was recorded while he still thought he had a chance of advancing -- and few period live albums come even close to capturing its excitement."

Answer this question: who played lead guitar on for what it's worth?
Student B:OK... The important part for answering this question is: The track features extensive and complex lead-guitar solos by Cassidy himself.
David Cassidy.

Student A:The cosmic distance ladder (also known as the extragalactic distance scale) is the succession of methods by which astronomers determine the distances to celestial objects. A real direct distance measurement of an astronomical object is possible only for those objects that are "close enough" (within about a thousand parsecs) to Earth. The techniques for determining distances to more distant objects are all based on various measured correlations between methods that work at close distances and methods that work at larger distances. Several methods rely on a standard candle, which is an astronomical object that has a known luminosity.

Answer this question: how do we measure the distance to other galaxies?
Student B:
OK... This is the relevant information: The cosmic distance ladder (also known as the extragalactic distance scale) is the succession of methods by which astronomers determine the distances to celestial objects.
The cosmic distance ladder ( also known as the extragalactic distance scale ).
