The solidity of bridge piers built on pilings depends largely on how deep the pilings are driven. Prior to 1700, pilings were driven to “refusal,” that is, to the point at which they refused to go any deeper. In a 1588 inquiry into the solidity of piers for Venice’s Rialto Bridge, it was determined that the bridge’s builder, Antonio Da Ponte, had met the contemporary standard for refusal: he had caused the pilings to be driven until additional penetration into the ground was no greater than two inches after twenty-four hammer blows.
Which one of the following can properly be inferred from the passage?
(A) The Rialto Bridge was built on unsafe pilings.
(B) The standard of refusal was not sufficient to ensure the safety of a bridge.
(C) Da Ponte’s standard of refusal was less strict than that of other bridge builders of his day.
(D) After 1588, no bridges were built on pilings that were driven to the point of refusal.
(E) It is possible that the pilings of the Rialto Bridge could have been driven deeper even after the standard of refusal had been met.
OFFICIAL EXPLANATION
The correct answer choice is (E). This interesting stimulus contains two definitions of “refusal:” an initial definition that implies refusal is a point at which pilings will go no further, and then a second, contemporary standards definition of refusal that reveals that refusal is a point at which additional penetration into the ground is no greater than two inches after twenty-four hammer blows. The stimulus is a fact set, and thus there is no conclusion present.
Answer choice (A): Although there was an inquiry into the solidity of the piers of the Rialto Bridge, the results of that inquiry are not disclosed. The only other information we are given is that the pilings of the Rialto Bridge met the contemporary standard of refusal, but this is not sufficient to indicate whether the pilings of this particular bridge were safe. Hence, this answer fails the Fact Test and is incorrect.
Answer choice (B): Similar to answer choice (A), we have insufficient information to make this judgment.
Answer choice (C): This answer is somewhat opposite of the information in the stimulus, which states that Da Ponte had met the contemporary standard of refusal.
Answer choice (D): This is another Opposite answer. The stimulus indicates that bridges built prior to 1700 were driven to the point of refusal.
Answer choice (E): This is the correct answer. As stated in the stimulus, “he had caused the pilings to be driven until additional penetration into the ground was no greater than two inches after twenty-four hammer blows.” The statement indicates that additional penetration was possible with a sufficient number of hammer blows.
