Earnings measu ures a worker's monthly carnings. CollegeDegree is an indicator variable that is equal to I for
workers who have a college degree, and O otherwise.Total Assets refers to the total asscts of the fim that employs
the worker. We take natural logarithm on both Earnings and Total_Assets. Earnings are measured in thousand
dollars, and Total Assets are measured in million dollars.【題組】9. Suppose Equation 2 is the correct model. That is, a firm's total asset size is a determinant of an employce's earnings. Are larger firms (measured by total asset size) more likely than smaller firms to employ college graduates?
(A) Larger firms are more likely to hire college graduates.
(B) Smaller firms are more likely to hire college graduates.
(C) All sizes of firms are equally likely to hire college graduates.
(D) We don't have sufficient information to answer this question.
(E) None of the abo bove choices (a)-(d).

【題組】1. Clearing the Air
Getting to zero carbon emissions won't save the world. We will need to remove carbon on a massive scale. To do that will require a planet-wide effort to match anything that humankind has ever achieved. Scientists and entrepreneurs are embarking on ambitious projects to remove carbon dioxide from ambient air and lock it away. In Arizona, an engineering professor shows me his "mechanical tree," a single one of which he says may someday be able to do the work of a thousand regular trees in capturing and storing CO2. In Australia, a leading oceanographer tells me that seaweed is salvation, if only we'd help it grow in giant aqua-gardens of kelp [海帶] and wakame [裙帶菜] that could harbor billions of tons of carbon dioxide.
What these efforts have in common is that they are geared in the long run to drag downward a number that climate experts agree holds the key to the health of the planet. That number is the atmospheric concentration of carbon dioxide, which for thousands of years had held stable at or a bit below 280 parts per million, until the industrial revolution kicked off in the middle of the 19th century. Today this critical number stands at some 420 parts per million—in other words, the percentage of CO2 in the atmosphere has risen roughly 50 percent since 1850. (National Geographic, Nov. 2023)
