The strength of a suspension bridge rests in part on how deep the towers are anchored into the ground. During the first wave of suspension bridge construction, consistent with best-practices at the time, regulations required engineers to drill holes for the towers such that the portion of the tower below ground accounted for at least half of the height of the tower. After conducting an inspection into the depth of the holes drilled for the towers of the Watergate Bridge, constructed over 50 years ago during the first wave of suspension bridge construction, regulators noted that updated architectural norms and theory advised that the bridge's towers should be reinforced to meet anticipated increases in usage.
Q. Which of the following is most strongly supported by the information above?
  • a)
    In light of current architectural theory, the Watergate Bridge should be closed until reinforcements can be added.
  • b)
    The original regulations for the depth of the suspension tower failed to anticipate future changes in demand or architectural theory.
  • c)
    Even with the implementation of the reinforcements advocated by the new architectural norms, the bridge will still not be safe.
  • d)
    In light of the regulators’ findings, every suspension bridge built during the first wave of construction must be updated to provide additional strength and carrying capacity.
  • e)
        The action advocated by current architectural theory should not be undertaken since there is no evidence to guarantee that the reinforcements will be adequate or advisable in light of future architectural research.
Correct answer is option 'B'. Can you explain this answer?

The conclusion of the stimulus is: "regulators noted that updated architectural norms and theory advised that the bridge's towers should be reinforced to meet anticipated increases in usage".
A. Since the bridge "should be reinforced to meet anticipated increases in usage," the author implies that the bridge is currently safe but should be reinforced to prepare for future changes in usage.
B. Two reasons are given for reinforcing: (1) "updated architectural norms" (2) "to meet anticipated increases in usage." Since the changes must be made for these two reasons, we can conclude that the original standards did not anticipate these two reasons/factors.
C. This answer states that the bridge still "will not be safe." The passage never states or implies that the bridge will not be safe. In fact, the words "to meet" seem to imply that the bridge will be safe with the changes.
D. The new architectural norms advocate the addition of supplemental reinforcements for the Watergate Bridge "to meet anticipated increases in demand." We cannot conclude that the historic regulations are faulty or that the situation with the Watergate Bridge mirrors that of every other bridge (i.e., since not every bridge is like the Watergate in its "anticipated increases in usage," we cannot conclude that every bridge needs the same reinforcements as the Watergate does).
E. The action should be undertaken because it is advised by regulators and is consistent with current design theory. The bridge was originally constructed "consistent with best-practices at the time" and the new reinforcements will help "meet anticipated increases in usage." The stimulus gives no indication that current best-practices should be abandoned simply because it is impossible to predict future theory.

Support for Option B:

Original Regulations:
- The original regulations required engineers to anchor suspension bridge towers with a portion below ground at least half of the height of the tower.
- This standard was based on best practices at the time of construction.

Failure to Anticipate Future Changes:
- The regulators noted that updated architectural norms and theory now advise for reinforcements to meet anticipated increases in usage.
- This suggests that the original regulations did not foresee the future changes in demand or architectural theory.

Conclusion:
- Based on the information provided, it is strongly supported that the original regulations for the depth of the suspension tower failed to anticipate future changes in demand or architectural theory.
- Therefore, Option B is the most strongly supported conclusion.

Similar GMAT Doubts

The accumulation of scientific knowledge regarding the environmental impact of oil well drilling in North America has tended to lag behind the actual drilling of oil wells. Most attempts to regulate the industry have relied on hindsight: the need for regulation becomes apparent only after undesirable events occur. The problems associated with oil wells’ potential contamination of groundwater—fresh water within the earth that supplies wells and springs—provide a case in point.When commercial drilling for oil began in North America in the mid-nineteenth century, regulations reflected the industry’s concern for the purity of the wells’ oil. In 1893, for example, regulations were enacted specifying well construction requirements to protect oil and gas reserves from contamination by fresh water. Thousands of wells were drilled in such a way as to protect the oil, but no thought was given to the possibility that the groundwater itself might need protection until many drinking-water wells near the oil well sites began to produce unpotable, oil contaminated water.The reason for this contamination was that groundwater is usually found in porous and permeable geologic formations near the earth’s surface, whereas petroleum and unpotable saline water reservoirs are generally found in similar formations but at greater depths. Drilling a well creates a conduit connecting all the formations that it has penetrated. Consequently, without appropriate safeguards, wells that penetrate both groundwater and oil or saline water formations inevitably contaminate the groundwater. Initial attempts to prevent this contamination consisted of sealing off the groundwater formations with some form of protective barrier to prevent the oil flowing up the well from entering or mixing with the natural groundwater reservoir. This method, which is still in use today, initially involved using hollow trees to seal off the groundwater formations; now, however, large metal pipe casings, set in place with cement, are used.Regulations currently govern the kinds of casing and cement that can be used in these practices; however, the hazards of insufficient knowledge persist. For example, the long-term stability of this way of protecting groundwater is unknown. The protective barrier may fail due to corrosion of the casing by certain fluids flowing up the well, or because of dissolution of the cement by these fluids. The effects of groundwater bacteria, traffic vibrations, and changing groundwater chemistry are likewise unassessed. Further, there is no guarantee that wells drilled in compliance with existing regulations will not expose a need for research in additional areas: on the west coast of North America, a major disaster recently occurred because a well’s location was based on a poor understanding of the area’s subsurface geology. Because the well was drilled in a channel accessing the ocean, not only was the area’s groundwater completely contaminated, but widespread coastal contamination also occurred, prompting international concern over oil exploration and initiating further attempts to refine regulations.Which one of the following most accurately states the main point of the passage?
