[1] The best reason to carpool is that it greatly reduces carbon emissions that pollute the air and harm the environment. If four people commit to carpooling in one car, it eliminates three cars from the daily drive. By leaving three cars at home, only one car remains on the road producing emissions. Multiply this reduction by numerous carpools in a particular city or state, and the benefits increase dramatically.
[2] Another reason more people should commit to carpooling is that it can save carpoolers a great deal of money. Imagine that a person drives five miles to work and five miles home. This short commute adds up to fifty miles per week. If the worker were to find four friends, each could drive one day per week. Each worker would therefore only put ten miles on his or her car each week. Over the course of a year, each member of the carpool could save hundreds of dollars in gas and car maintenance.
[3] A surprising number of people are unwilling to carpool. They claim that it is simply not convenient. They do not wish to spend extra time each day picking up other people in the morning and dropping them off at home. They also argue that carpooling limits them to a rigid schedule, so they cannot stop on their way to work in the morning, stay late at work, or run an errand on the way home, These concerns, however, are minor.
Question
Monty knows that readers may argue that carpooling is inconvenient. He wants to add some sentences to paragraph 3 that address that concern.


Which option presents the ,begin emphasis,best,end emphasis, argument against readers' concerns?


1.
As long as carpoolers plan ahead and are willing to compromise, carpooling poses little inconvenience. For example, carpoolers might agree to leave a little earlier in the morning to allow time for a breakfast snack or stay at the office a little later on some afternoons. Drivers can still run errands at lunchtime on the days they drive the group.
2.
True, carpooling is inconvenient. It requires sacrifices such as getting up earlier in the morning (and possibly losing sleep), losing the freedom to make one's own plans, and taking an indirect route when traveling home.
3.
In order to truly overcome the issue of inconvenience, carpoolers must be willing to sacrifice. Rather than selfishly driving, they can give up a small amount in each day to make a big impact on society.
4.
People must maintain perspective. They must understand that these inconveniences are not real problems. It is unrealistic for people to expect to drive whenever and wherever they wish.
