Read the following passage about the future of energy and mark the letter A, B, C, or D on your answer sheet to indicate the best answer to each of the following questions.

     [I] As the world grapples with the finite nature of fossil fuel reserves and the detrimental impact of climate change, the future of energy undeniably lies in renewable sources. [II] Scientists and engineers are making substantial advancements in the development of technologies that more efficiently harness solar, wind, hydro, and geothermal energy. [III] Although the transition to these renewable sources presents significant challenges, it is also regarded as a pivotal step towards establishing a sustainable and resilient energy system. [IV]

     One of the most promising advancements in renewable energy is the enhancement of solar panel efficiency. Progress in photovoltaic technology has led to the creation of panels that convert a higher proportion of sunlight into electricity. Likewise, wind turbines are becoming more and more efficient. They are capable of generating power even under low-wind conditions. These innovations are essential for making renewable energy more feasible and accessible to a broader population.

     However, the transition to renewable energy is fraught with obstacles. The intermittent nature of sources like solar and wind necessitates reliable storage solutions to ensure a consistent power supply. Although battery technology has seen significant improvements, further advancements are imperative to meet growing demand. Moreover, new infrastructure for distributing renewable energy requires expansion and upgrading to accommodate these new power sources.

     The economic impact of transitioning to renewable energy is another critical consideration. While the initial investment in renewable energy infrastructure can be substantial, the long-term benefits include reduced energy costs and job creation in the green energy sector. Governments and private enterprises are increasingly acknowledging the necessity of investing in renewable energy projects, which is crucial for fostering innovation and diminishing reliance on fossil fuels.

     Ultimately, the future of energy hinges on our capacity to innovate and adapt. By continuing to invest in research and development, improving infrastructure, and addressing economic and technical challenges, we can transition towards a more sustainable and environmentally friendly energy system.

Foot-racing is a popular activity in the United States. It is seen not only as a competitive sport but also  as  a  way  to  exercise,  to  enjoy  the camaraderie  of  like-minded  people,  and  to  donate  money  to  a good  cause.  Though  serious  runners  may  spend  months  training  to  compete,  other  runners  and  walkers might not train at all. Those not competing to win might run in an effort to beat their own time or simply to enjoy the fun and exercise. People of all ages, from those of less than one year (who may be pushed in strollers)  to  those  in  their  eighties,  enter  into  this  sport.  The  races  are  held  on  city  streets,  on  college campuses, through parks, and in suburban areas, and they are commonly 5 to 10 kilometers in length.
The  largest  footrace  in  the  world  is  the  12-kilometer  Bay  to  Breakers  race  that  is  held  in  San Francisco every spring. This race begins on the east side of the city near San Francisco Bay and ends on the west side at the Pacific Ocean. There may be 80,000 or more people running in this race through the streets and hills of San Francisco. In the front are the serious runners who compete to win and who might finish  in  as  little  as  34  minutes.  Behind  them  are  the  thousands  who  take  several  hours  to  finish.  In  the back of the race are those who dress in costumes and come just for fun. One year there was a group of men who dressed like Elvis Presley, and another group consisted of firefighters who were tied together in a  long  line  and  who  were  carrying  a  fire-hose.  There  was  even  a  bridal  party,  in  which  the  bride  was dressed  in  a  long  white  gown  and  the  groom  wore  a  tuxedo.  The  bride  and  groom  threw  flowers  to bystanders, and they were actually married at some point along the route.
