GMAT Reading Comprehension Practice Questions

Tuned LED systems are cheaper to install and operate than the fluorescent lamps they replace.

Most visitors cannot tell a spectrally tuned gallery from a conventionally lit one.

The wavelengths that tuned LEDs must retain so that colors remain visible still produce cumulative damage in many common colorants.

Museums that employ microfade testing continue to rotate sensitive objects off view on a fixed schedule.

Some early LED installations failed to deliver their promised energy savings.

It has been conclusively refuted by the temperature measurements taken inside occupied mounds.

Were it correct, colonies exposed to unlike air currents would build along unlike axes.

It was proposed earlier than the thermoregulation hypothesis.

It is the explanation the author regards as the most economical account of the mounds' geometry.

It accounts for the rounded mounds more readily than for the magnetic mounds.

demonstrate that the condition attached to the author's endorsement is now feasible to satisfy

prove that spectrally tuned light is harmless to fugitive materials

argue that this technique ought to replace annual exposure budgets

illustrate how ultraviolet wavelengths damage historic textiles

explain why the 50 lux ceiling was originally adopted for works on paper

was the only forge in its region that produced nails for sale to distant merchants.

sold fewer nails to local carpenters afterward, because those carpenters stopped commissioning work from it.

chose the quick-struck shape because it was the form local carpenters requested most frequently.

had previously produced a less uniform range of heads.

demonstrates that regional tradition governed its output more than market pressures did.

illustrate the hydraulic penalties associated with the semicircular arch

describe the material from which medieval piers were built

identify a factor that limited where the improved arch forms were adopted

show that medieval builders generally lacked access to skilled labor

explain how builders reduced the outward thrust of their arches

Retraining programs for displaced workers

Outsourcing middle-skill jobs to lower-wage countries

Technological innovation and automation

Regulatory interventions to slow automation

Education and social welfare programs

Smaller cities show lower elasticity (0.08) than mid-sized cities (0.10)

Smaller cities exhibit higher elasticity (0.12) than megacities (0.08)

Elasticity values are not specified for the MAR model in the passage

Elasticity decreases from 0.12 to 0.08 as cities grow larger

Elasticity is constant at 0.10 regardless of city size

The logarithmic scaling law of the MAR model accurately describes productivity gains in emerging sectors.

Patent citation networks provide definitive evidence against cross-industry knowledge spillovers.

The relative importance of MAR versus Jacobs mechanisms depends on both city size and industry maturity.

MAR mechanisms completely dominate Jacobs effects in all cities, regardless of size or sector maturity.

Jacobs' combinatorial diversity model predicts urban productivity better than the MAR model in all contexts.

The lack of regulatory mandates requiring stakeholder-centric policies in all regions.

The difficulty in aligning stakeholder interests with industry-specific externalities.

The selection bias in empirical studies linking stakeholder practices to financial performance.

The inability to quantify intangible stakeholder benefits consistently across industries.

The conflict between short-term profitability and long-term value creation.
