Art expert: If a painting is from the Hudson River School of the mid-nineteenth century United States, it will display a romantic reverence for landscape, portraying pastoral

scenes in which humans and nature coexist peacefully. The painting that was recently discovered in the attic of the old town hall dates from the 1850s and portrays a

pastoral landscape in which two couples are having a peaceful picnic. So the painting must be from the Hudson River School.

The critic’s argument is flawed in that it

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?

The artist has correctly determined that to make the largest possible square grid from the available tiles, she must use all of the except for those in the group of X tiles. Moreover, if she uses all of the tiles except for those in the group with X tiles and those in the group with Y tiles, she could make a smaller square grid.

select for X for Y the values that are consistent with the information provided. Make only two selections, one in each column.
