Select TWO options that apply to the structure above:

Question

BlackTom AI · Accepted Answer

Begin by identifying which statements could plausibly describe the structure in the image and the context provided.
Option 1: Innovative technology of pre-stressed concrete. The image shows a large, modern civil structure with long spans and heavy concrete elements, which commonly employ pre-stressing to improve capacity and reduce deflection. This makes the statement plausible and likely correct, as prestressing is a hallmark of advanced concrete construction.
Option 2: Presence of castellated beams. Castellated beams are beams with a perforated or honeycomb-like profile used to increase depth efficiency and reduce weight while maintaining strength. In the visible framework, there is no clear evidence of castellations or the characteristic perforations in the beams; without a closer view, this remains uncertain and less likely.
Option 3: 75 meter (246 ft) free span. If the structure is a bridge-like concrete frame with long cantilevered or free spans, a 75-meter clear span is within the realm of prestressed concrete design, especially for highway or large building frames. Given the scale seen in the image, this is a plausible specification and could indeed be the stated span.
Option 4: Cycloid geometry. Cycloid geometry refers to a curve used in certain arch or track designs, but in typical concrete frames and bridges, cycloidal forms are not a standard primary geometry for major spans. The image shows a more linear, box-like structure rather than a cycloidal profile, making this option less likely.
In sum, the most consistent pair with the visible evidence and typical design practices are: the use of innovative pre-stressed concrete technology, and a substantial free span such as 75 meters. The other options either lack clear visual support (castellated beams) or contradict common geometric forms for such structures (cycloid geometry).
