Explanation:

First Question (Trade - off in the cartoon)

In economics, a trade - off refers to a situation where choosing more of one thing means having less of another. When it comes to cars, generally, larger cars (with more weight and size) tend to have lower fuel efficiency because they require more energy to move, and smaller cars tend to be more fuel - efficient. The other options: size vs price is not a typical fundamental trade - off in terms of the car's performance and resource use; price vs fuel efficiency is more about cost and efficiency but not as fundamental as size and fuel efficiency; speed vs price is also not the core trade - off related to the car's design and resource consumption like size and fuel efficiency. So the trade - off of size of the car vs fuel efficiency is the correct one.

Economics is mainly concerned with how societies, businesses, and individuals allocate scarce resources. Monetary policy is a tool used by central banks to manage the economy, not the main idea of economics. Business decisions are a part of economic activity but not the overarching main idea. Efficiency of production is a part of how resources are allocated (producing goods efficiently is part of using scarce resources well), but the core idea is the allocation of scarce resources since resources like labor, capital, and natural resources are limited, and economics studies how to distribute them among different needs and wants.

Answer:

size of the car vs fuel efficiency (the option with the blue dot next to "size of the car vs fuel efficiency")
