Virtually all health experts agree that second-hand smoke poses a serious health risk. After the publication of yet another research paper explicating the link between exposure to second-hand smoke and a shorter life span, some members of the State House of Representatives proposed a ban on smoking in most public places in an attempt to promote quality of life and length of lifespan. Which of the following, if true, provides the most support for the actions of the State Representatives?

• The amount of damaging chemicals and fumes released into the air by cigarette smoke is far less than the amount released from automobiles, especially from older models.

• Banning smoking in most public places will not considerably reduce the percent of the population in the state in question that smokes.

• The state whose legislators are proposing the tough smoking legislation has a relatively high percent of its population that smoke.

• Another state that enacted a similar law a decade ago saw a statistically significant drop in lung-cancer rates among non-smokers.

• A nearby state up-wind has the highest number of smokers in the country.

Net Neutrality stipulates that Internet service providers (ISP) cannot partition their bandwidth such that different types of Internet communications have different maximum bandwidth capacities. For example, an ISP cannot relegate high bandwidth voice-over-IP (VoIP) traffic to a separate tunnel in an attempt to ensure that users of low-bandwidth functions such as plain-text email are not slowed down by the high-bandwidth users. Some individuals support implementing Net Neutrality on the principle that one group (i.e., users of high-bandwidth services) should not be effectively penalized for the actions of another group (i.e., users of slow-bandwidth services, who have a special traffic lane carved out for them, thereby slowing high-bandwidth users). Which of the following, if true, most seriously weakens the argument of the supporters of Net Neutrality mentioned above?

• The jobs of many high-bandwidth users require these individuals to use high-bandwidth services.

• Placing no restrictions on the bandwidth of individuals who use high-bandwidth services would force ISPs to purchase massive amounts of expensive additional bandwidth, disproportionately increasing the price of access for low-bandwidth users.

• A strong and well respected lobbying firm recently revealed it has been hired by large telecommunications firms to oppose Net Neutrality on the grounds that it infringes upon a private company's ability to do business.

• One country that mandated Net Neutrality saw a decrease in satisfaction of Internet users.

• A recent court ruling upheld the principle that technology companies cannot discriminate in whom they serve or how they serve users.

Most scientists believe that the decay of the ozone layer is a cause of global warming. With a weaker ozone layer, additional wavelengths of light reach the earth. However, the danger posed by ozone decay is not limited to global warming. The decay of the ozone layer, which enables more harmful wavelengths of light to reach the earth's surface, is also believed to cause permanent eye damage in some animals. Which of the following is most strongly supported by the statements above?

• All wavelengths of light from the sun that damage the eyes of animals are blocked by a healthy ozone layer.

• Some animals do not experience damage to their eyes when exposed to unfiltered waves of light.

• Only a handful of animal species live in places where they are exposed to the damaging light waves.

• The rising temperature of the earth poses a severe threat to animals.

• Some wavelengths of light that engender eye damage in certain animals are more likely to hit the earth due to ozone decay.

Which of the following most logically follows from the statements above?

• A well-written detective story consists of an investigation being undertaken by a competent and incompetent investigator.

• Some authors use an incompetent investigator to show the complexities of an investigation.

• Authors never write stories with incompetent investigators who solve a case correctly.

• Authors can use the separate investigative accounts to make predicting the correct outcome of the investigation more difficult.

• Authors write stories with competent and incompetent investigators to show the complexity of real life.

Political Commentator: In order for a democracy to flourish, it is essential that political and journalistic freedom of expression exist. Even if commentators voice ideas that do not support the current government, a society is strengthened by the variety of views expressed. Yet, our government continues to exercise a stranglehold on certain forms of speech. It is essential that the government loosen its control on the media. Despite the potential short-term instability this may cause the country, it will strengthen the long-term health of the country. Which of the following expresses the conclusion of the argument?

• The government is exercising too much control over the media

• The government needs to open the media and release its hold on certain forms of speech

• Democracy requires a strong and free press

• Even ideas not supportive of democracy can strengthen a government

• The future of the media lies in the hands of the government

Years ago, some in the government's intelligence community feared the work of telecommunications researchers at then-emerging private security firms. The government experts concluded that these private firms posed the biggest risk to successful government espionage. As the private security firms began publicly releasing and advertising encryption algorithms and other security products, these government experts saw support for their conclusion when an encryption algorithm that government experts could not break began appearing in countless emails. Which of the following, if true, most weakens the conclusion of the government experts referred to above?

• Shortly before the government experts reached their conclusions, two private security companies each claimed to have developed "the world's strongest email encryption algorithm"

• The private security firms' decision to advertise their products and sell them publicly led to other members of the private sector and academia scrutinizing the encryption algorithms.

• An open-source encryption algorithm, developed by an academic and freely available from popular websites, is recognized by numerous ex-government code breakers as the most unbreakable algorithm ever developed.

• An enemy government recently succeeded in placing a spy within the government espionage operations referred to above.

• To strengthen the reputation of the private security firms, employees of these firms publish information about the strength of their products and the benefits of using them.

• All computer programs must lack creativity in order to be well received.

• Some computer scientists entirely disregarded creativity and chose instead to pursue profit.

• A program cannot be both creative and profitable.

• Computer scientists are obsessed with the profitability of their work.

• Non-profit institutions use large amounts of software.

Marketing executives in television work with a relatively stable advertising medium. In many ways, the television ads aired today are similar to those aired two decades ago. Most television ads still feature actors, still run 30 or 60 seconds, and still show a product. However, the differing dynamics of the Internet pose unique challenges to advertisers, forcing them to adapt their practices and techniques on a regular basis. In the early days of Internet marketing, online advertisers employed banner and pop-up ads to attract customers. These techniques reached large audiences, generated many sales leads, and came at a low cost. However, a small number of Internet users began to consider these advertising techniques intrusive and annoying. Yet because marketing strategies relying heavily on banners and pop-ups produced results, companies invested growing amounts of money into purchasing these ad types in hopes of capturing market share in the burgeoning online economy. As consumers became more sophisticated, frustration with these online advertising techniques grew. Independent programmers began to develop tools that blocked banner and pop-up ads. The popularity of these tools exploded when the search engine Google, at the time an increasingly popular website fighting to solidify its place on the Internet with giants Microsoft and Yahoo, offered free software enabling users to block pop-up ads. The backlash against banner ads grew as new web browsers provided users the ability to block image-based ads such as banner ads. Although banner and pop-up ads still exist, they are far less prominent than during the early days of the Internet. A major development in online marketing came with the introduction of pay-per-click ads. Unlike banner or pop-up ads, which originally required companies to pay every time a website visitor saw an ad, pay-per-click ads allowed companies to pay only when an interested potential customer clicked on an ad. More importantly, however, these ads circumvented the pop-up and banner blockers. As a result of these advantages and the incredible growth in the use of search engines, which provide excellent venues for pay-per-click advertising, companies began turning to pay-per-click marketing in droves. However, as with the banner and pop-up ads that preceded them, pay-per-click ads came with their drawbacks. When companies began pouring billions of dollars into this emerging medium, online advertising specialists started to notice the presence of what would later be called click fraud: representatives of a company with no interest in the product advertised by a competitor click on the competitor's ads simply to increase the marketing cost of the competitor. Click fraud grew so rapidly that marketers sought to diversify their online positions away from pay-per-click marketing through new mediums. Although pay-per-click advertising remains a common and effective advertising tool, marketers adapted yet again to the changing dynamics of the Internet by adopting new techniques such as pay-per-performance advertising, search engine optimization, and affiliate marketing. As the pace of the Internet's evolution increases, it seems all the more likely that advertising successfully on the Internet will require a strategy that shuns constancy and embraces change. According to the passage, the largest point at which the television and Internet differ as an advertising medium is:

• The type of individual each medium reaches

• Whether the medium is interactive

• The pace at which the medium evolves

• The cost of advertising with each medium

• Whether each medium contains drawbacks
