Many advocate cost-benefit assessment of environmental policies. Although some costs and benefits are already in monetary terms, others, such as effects on the quality of

However, while this appears to treat everyone's interests alike, it is biased against the interests of certain groups because
Plague bacilli, the microorganisms that cause bubonic plague, are typically carried from rodents to humans by fleas. Although the bubonic plague epidemic that devastated
Europe in the Middle Ages probably originated with certain species of plague-infected rodents from central Asia, the nomadic peoples of central Asia never contracted plague.
Therefore, since they undoubtedly had some contact with infected rodents, it is likely that these central Asian peoples had physiological immunity against plague bacilli.
Which of the following, if true, most seriously weakens the argument?
In 90 percent of the commercial airline accidents last year, one or another of a group consisting of only 18 percent of the world's commercial airlines was involved.

Public health professional: The Shoreville Department of Environmental Services (OES) has Inspected area beaches for pathogenic bacteria for more than 20 years. Currently, DES monitors 50 freshwater beaches and 10 coastal beaches on a weekly basis. Program participation by owners of beaches that are open to the public is voluntary. Owners of beaches who choose not to participate in the Program are allowing the public to recreate on entirety unmonitored beaches.
The DES now proposes adoption of the Adopt-a-Beach Program, designed to promote health and environmental education as well as public involvement in the protecting of public beaches. The program would require DES to collect biological data from all area beaches. It will also help reduce the number of beach advisories, whereby the public must be warned of dangerous conditions on certain beaches.
On the basis of the pubic heath professional's statement, indicate which of the following is most likely True of the Adopt-a-Beach program at the time of writing, and indicate which of the following is most likely False (A the program at the time of writing. Make only two selections, one in each column.

Welleby’s Plan
The water In the underground water table beneath the town of Welleby is moderately saline— 20,000millkjrarns of salt per liter of water (mg/L), or roughly half as saline as ocean water. To lower the level of the water table and thus prevent agricultural land from being inundated with salt water, the town plans to pump water from the table at a rate of 450kiloliters per day (kL/day) into a large shallow pond, allowing much of the water to evaporate. The town plans to divert 10percent of the water pumped from the water table to supplement Us supply of drinking water, which Is currently piped In from great distances. Due to the water's supply, the town intends to construct a desalination plant to treat the diverted water for use as drinking water.
Desalination Types
Comparison
Welleby is deciding among the following three desalination methods.
Reverse Osmosis (RO): Water Is pushed through a membrane, leaving salts behind. RO systems can handle a large range of water flow rates and use relatively little energy. However, RO membranes are expensive and must be replaced every 2 to 5 years. There is also a possibility that bacteria can grow on the membrane. Introducing tastes and odors Into the desalinated water.
Multi-Effect Distillation (MED): Saline water Is heated to produce water vapor, from which Is condensed potable fresh water. This process requires large amounts of energy, regardless of the salinity of the source water. It becomes more cost effective as water volumes increase.
Electrodialysis (ED): Electricity is used to selectively move salts through a membrane. Consumption of energy Is directly proportional to the salinity of the water to be treated, so with higher salinities the process rapidly becomes more costly than other methods. ED membranes need to be replaced every 7 to 10years.
Based on the information provided, which one of the following benefits to Welleby is most likely to result from Its building a desalination plant?

A certain municipality is deliberating over whether it will adopt a policy that would require it to have a balanced budget each year. Proponents prefer the policy because it would keep the municipality from spending more money than it receives, but critics argue that the policy should allow for exceptions so the municipality can respond to crises that might temporarily require spending beyond that amount.
From among the options below, select for Response to the critics and for Reply to that response two statements such that the first, if true, most strongly undermines the critics' argument and the second, if true, is the critics' strongest reply to that response. Make only two selections, one in each column.
West River Glen is deciding which network architecture should replace its old copper telephone lines. The town will replace 300 miles of Outside Plant (OSP) cable that will serve approximately 2,500 homes.
The first option is to install a Fiber to the Home (FTTH) system architecture that uses fiber-optic cable to transmit signals from the source to each home. The advantages of this architecture include greater bandwidth capabilities, less signal loss, and slightly lower new-cable deployment costs than the second option. Hybrid Fiber-Coax (HFC).
An HFC network integrates fiber-optic cables and devices with coaxial cables.
This will cost the town substantially less money for internal equipment and for customer installations. However, the coaxial cable does not last as long as fiberoptic cable and will thus need to be replaced more frequently, resulting in higher long-term maintenance expenses.
The town believes that either the FTTH or HFC architectures will be capable of serving the communities' data and television needs for the next 30 years.
According to the information provided, which of the following attributes is an advantage of HFC network architecture as compared with FTTH architecture?
