1. The correct answer is (D). This is a combination main idea and interpretation question. If you cannot easily answer this question, reread the selection. The author clearly states his opinion about the XYZ Process in the first sentence. The rest of the selection provides an abundance of facts to support his conclusion.

1. The correct answer is (A). The first sentence states that all shafts except stair shafts in which the stairs do not continue to the roof must be carried at least two feet above the roof. Elevator shafts must extend those two feet. The second sentence makes the exception that elevator shafts need not have a skylight.

2. The correct answer is (B). The 15.75-square-foot skylight over the 20-square-foot pipe shaft covers more than three-quarters of the area of the shaft. All other skylights are inadequate.

1. The correct answer is (A). Presumably, a modern fire alarm system enables alarms to be transmitted and received most rapidly and accurately. The more quickly the firefighters can respond, the more quickly they can control the fire and the smaller it will be.

2. The correct answer is (D). A second search is very much in order, but it should be made by a different group of firefighters.

1. The correct answer is (B). The main reason a fiberglass ladder would be used in place of an aluminum ladder is if there were concerns about conductivity or the risk of electrical shock from nearby electrical wires.

Fiberglass and aluminum are not flammable, choice (C), nor are they susceptible to rusting, choice (D).

2. The correct answer is (B). Kerosene and fine steel wool will effectively remove a thin layer of rust.  Vaseline, choice (A), can prevent rust but not remove it. A sharp knife, choice (C), might chip off thick crusty rust but not a thin coat. A dry cloth alone, choice (D), will not remove rust.

1. The correct answer is (A). Choice (C) would be slightly longer. Choices (B) and (D) are impossible from the given starting point.

1. The correct answer is (C). The front door enters directly into the living room. The door to the kitchen from the garage is a secondary entrance. There is no anteroom indicated in front of the living room.
