question:
Context: How quickly is the human population growing? If we look at worldwide human population growth from 10,000 BCE through today, our growth looks like exponential growth. It increased very slowly at first, but later grew faster and faster as the population increased in size ( Figure 1.1). And recently, the human population has increased at a faster pace than ever before. It has taken only 12 years for the worlds population to increase from six billion to seven billion. Considering that in the year 1804, there were just one billion people, and in 1927, there were just two billion people (thats 123 years to increase from 1 to 2 billion), the recent increase in the human population growth rate is characteristic of exponential growth. Does this mean there are unlimited resources? Worldwide human population growth from 10,000 BCE through today. On the other hand, if you look at human population growth in specific countries, you may see a different pattern. On the level of a country, the history of human population growth can be divided into five stages, as described in Table 1.1. Some countries have very high birth rates, in some countries the growth rate has stabilized, and in some countries the growth rate is in decline. Stage 1 2 3 4 5 Description Birth and death rates are high and population growth is stable. This occurred in early human history. Significant drop in death rate, resulting in exponential growth. This occurred in 18th- and 19th-century Eu- rope. Population size continues to grow. Birth rates equal death rates and populations become stable. Total population size may level off. The United Nations and the U.S. Census Bureau predict that by 2050, the Earth will be populated by 9.4 billion people. Other estimates predict 10 to 11 billion. There are two different beliefs about what type of growth the human population will undergo in the future: 1. Neo-Malthusians believe that human population growth cannot continue without destroying the environment, and maybe humans themselves. 2. Cornucopians believe that the Earth can give humans a limitless amount of resources. They also believe that technology can solve problems caused by limited resources, such as lack of food. The Cornucopians believe that a larger population is good for technology and innovation. The 5-stage model above predicts that when all countries are industrialized, the human population will eventually level out. But many scientists and other Neo-Malthusians believe that humans have already gone over the Earths carrying capacity. That means, we may have already reached the maximum population size that can be supported, without destroying our resources and habitat. If this is true, then human overpopulation will lead to a lack of food and other resources. Overpopulation may also lead to increased disease, and/or war. These problems may cause the population of humans to crash. If these issues are not controlled, could the human population go extinct? Which of the above theories makes sense to you? Why? 
 Question: which is the last stage of human population growth?
answer:
total population size may level off.

Context: Coming off their come-from-behind win over the Dolphins, the Broncos traveled to Arrowhead Stadium for an AFC West rematch with the Kansas City Chiefs. The Broncos jumped out to a 14-0 lead on their first two possessions in the first quarter, with quarterback Peyton Manning throwing a pair of touchdown passes a 23-yarder to wide receiver Demaryius Thomas and a 15-yarder to running back C. J. Anderson. A 22-yard field goal by placekicker Connor Barth increased the Broncos' lead to 17-0 early in the second quarter. The scoring play occurred after the Broncos' special teams fooled the Chiefs with a fake punt run by safety David Bruton and a fourth-down conversion by Anderson. The Chiefs got on the scoreboard later in the second quarter, with quarterback Alex Smith connecting on a 20-yard touchdown pass to tight end Anthony Fasano. The Broncos' offense subsequently marched down the field, but had to settle on a 24-yard field goal by Barth just before halftime. The Chiefs' defense forced a fumble off Manning deep in Broncos' territory on the Broncos' first possession of the second half, but had to settle on a 39-yard field goal by placekicker Cairo Santos. Barth added two more field goals a 30-yarder midway through the third quarter and a 33-yarder early in the fourth quarter to increase the Broncos' lead to 26-10. The first field goal came after a DeMarcus Ware interception of Smith on a deflected pass, while the second field goal came after Chiefs' cornerback Marcus Cooper muffed a punt. The Chiefs narrowed the Broncos' lead, with Smith throwing a 12-yard touchdown pass to running back Jamaal Charles. However, Broncos' safety T. J. Ward knocked away a two-point conversion pass from Smith intended for Fasano that would have brought the Chiefs to within a one-score deficit. Barth added one more field goal a 37-yarder midway through the fourth quarter. The Broncos' defense subdued the Chiefs for the remainder of the game. With the win, the Broncos swept the Chiefs for a third consecutive season. Peyton Manning improved his personal record to 11-1 all-time in games against the Chiefs. 
 Question: What quarter did Barth add the 37 yard field goal?
answer:

the fourth quarter
