QUESTION: 41

Ergonomics is the science of designing and arranging workspaces so that people and objects interact efficiently and safely. Lack of attention to ergonomics causes thousands of workers to suffer repetitive stress injury, eye fatigue, muscle soreness, and many other medical problems each year.
Adequate lighting, well-designed chairs, and clutter-free work areas contribute to effective ergonomic design. The opportunity to take short breaks every hour or two, especially for deskbound workers, is also helpful. It’s also important for workers to avoid performing the same movements over and over for hours at a time. Variety in the type of work being done can decrease the chance of injury.
According to this passage, ___________ .

adequate lighting and well-designed chairs, although important, have nothing to do with ergonomics
repetition in the type of work people do helps them accomplish their tasks safely and efficiently
short breaks aren’t important for deskbound employees because they do little heavy labor
ergonomic design also includes keeping work areas well lit and clutter free

Answer(s): D

Explanation:

The passage states that adequate lighting and well-designed chairs are part of ergonomic design, so Choice "adequate lighting and well-designed chairs, although important, have nothing to do with ergonomics" is incorrect.
The passage states that repetitious work can cause injury, so Choice "repetition in the type of work people do helps them accomplish their tasks safely and efficiently" is incorrect.
The passage states that desk-bound workers should take breaks, so Choice "short breaks aren’t important for deskbound employees because they do little heavy labor" is incorrect.

QUESTION: 43

Electricity is the most inefficient and costly way to heat a home. One kilowatt-hour of electricity creates about 3,400 British thermal units (BTUs). (BTUs are a standard heat measurement.) The price of electricity per kilowatt-hour is between $0.10 and $0.25 or between $29.35 and $73.13 per million BTUs.
In contrast, fuel oil, which produces 140,000 BTUs per gallon, costs about $8.33 to $13.89 per million BTUs. Natural gas, which produces 100,000 BTUs per therm, can be purchased for $5.00 to $22.50 per million BTUs. Oak firewood, which produces 26,000,000 BTUs per cord, costs $5.77 to $13.46 per million BTUs.
Choosing the right heating method for your home, based on the cost of fuel, may be more expensive at installation but will be cheaper in the long run.
According to the above passage, a BTU ________________.

is an unusual method of measuring heat
stands for "British thermal unit"
is the abbreviation for a "big thermal unit"
can heat a 9 × 12 room

Answer(s): B

Explanation:

The passage says that BTUs are the standard measure of heat, so Choice "is an unusual method of measuring heat" is incorrect.
BTU stands for British thermal unit, so Choice "is the abbreviation for a "big thermal unit" is incorrect. Nothing in the passage supports Choice "can heat a 9 × 12 room."

Answer(s): D

Explanation:

The passage shows that fuel oil can be more expensive than other heating methods, so Choice "heating with fuel oil is always cheaper than other methods" is incorrect.
