QUESTION: 329

Archaeologists seeking the location of a legendary siege and destruction of a city are excavating in several possible places, including a middle and a lower layer of a large mound. The bottom of the middle layer contains some pieces of pottery of type 3, known to be from a later period than the time of the destruction of the city, but the lower layer does not.
The force of the evidence cited above is most seriously weakened if which of the following is true?

Gerbils, small animals long native to the area, dig large burrows into which objects can fall when the burrows collapse.
Pottery of types 1 and 2, found in the lower level, was used in the cities from which, according to the legend, the besieging forces came.
Several pieces of stone from a lower-layer wall have been found incorporated into the remains of a building in the middle layer.
Both the middle and the lower layer show evidence of large-scale destruction of habitations by fire.
Bronze ax heads of a type used at the time of the siege were found in the lower level of excavation.

After the national speed limit of 55 miles per hour was imposed in 1974, the number of deaths per mile driven on a highway fell abruptly as a result. Since then, however, the average speed of vehicles on highways has risen, but the number of deaths per mile driven on a highway has continued to fall.
Which of the following conclusions can be properly drawn from the statements above?

The speed limit alone is probably not responsible for the continued reduction in highway deaths in the years after 1974.
People have been driving less since 1974.
Driver-education courses have been more effective since 1974 in teaching drivers to drive safely.
In recent years highway patrols have been less effective in catching drivers who speed.
The change in the speed limit cannot be responsible for the abrupt decline in highway deaths in 1974.
