331

Read the text: 'The ancient stone tablet was written in three scripts: Egyptian hieroglyphs, Demotic script, and Ancient Greek, which allowed nineteenth-century linguists to finally decipher the previously unreadable hieroglyphs.' What can be inferred?

A Scholars already understood Ancient Greek prior to deciphering the hieroglyphic script. B Ancient Greek was invented by nineteenth-century linguists. C Egyptian hieroglyphs were spoken by ordinary Greek farmers. D Demotic script was completely unrelated to the historical Egyptian language.

332

Read the statement: 'The central government began offering generous subsidies to homeowners installing rooftop solar panels, but canceled funding for households that failed to replace inefficient incandescent lighting.' What can be inferred?

A The policy aimed to combine renewable energy generation with domestic energy conservation. B Incandescent bulbs generate more domestic heat than rooftop solar systems. C The government wanted to prevent residential properties from using solar energy. D Rooftop solar panels function only when connected to incandescent light fixtures.

333

Read the passage: 'Geologists determined that the granite layer showed signs of glacial striations (deep scratches), even though the surrounding desert currently experiences summer temperatures exceeding 45 degrees Celsius.' What can be inferred about the region?

A The region's climate was substantially colder in ancient geological history. B Windblown desert sand creates identical scratch patterns to massive ice sheets. C Glaciers routinely form in arid desert valleys during cold winter nights. D Granite rocks cannot withstand temperatures above freezing point.

334

Read the statement: 'The tech company recalled its newest wireless earbuds after thousands of users complained that the microphone picked up street background noises louder than human speech.' What can be inferred?

A The product's audio filtering or noise-cancellation engineering was flawed. B The earbuds were designed exclusively for listening to music in recording studios. C Consumers prefer using bulky wired headphones in urban environments. D The earbuds suffered from defective internal lithium battery units.

335

Read the sentence: 'Unlike coastal marine fish that continuously drink seawater to prevent dehydration, freshwater fish actively avoid swallowing water and excrete large volumes of dilute urine.' What can be inferred about freshwater fish?

A Their internal bodily fluids have a higher salt concentration than the surrounding freshwater environment. B Freshwater fish are at constant risk of drying out from salt loss. C Seawater fish absorb excess water through their gills without effort. D Freshwater environments contain more dissolved mineral salts than oceans.

336

Read the statement: 'The university observed a sharp decline in library foot traffic corresponding directly with the digitization and remote access rollout of its complete academic journal catalog.' What can be inferred?

A Students and researchers previously visited the physical library largely to consult hardcopy academic resources. B University students stopped reading academic journal articles altogether. C The library building was permanently demolished following digitization. D Digital journal catalogs are harder to search than physical library card systems.

337

Read the sentence: 'The national park service mandated that all hikers carry bear-proof canisters for food storage after human-bear encounters doubled in backcountry campsites.' What can be inferred?

A Unsecured hiker food attracts bears to designated backcountry campsites. B Bears in the national park have developed the ability to open sealed metal canisters. C The bear population in the park has quadrupled over the past week. D Hikers are safer if they leave food items scattered along the trails.

338

Read the passage: 'Although the clinical trial demonstrated that the experimental drug shrank tumors in mice, the pharmaceutical firm halted human trials after healthy human volunteers reported severe liver toxicity.' What can be inferred?

A Efficacy in animal models does not guarantee safety or tolerability in human physiology. B Mice possess identical biochemical liver pathways to human beings. C The experimental drug cured human cancer patients without any side effects. D Pharmaceutical trials should never test compounds on animal subjects first.

339

Read the text: 'The city council voted to replace all sodium-vapor streetlights with LED fixtures after a study projected a forty percent reduction in municipal electricity expenditures.' What can be inferred?

A LED lighting fixtures are more energy-efficient than traditional sodium-vapor lamps. B Sodium-vapor lamps provide better illumination than modern LED diodes. C The city council intends to plunge downtown streets into total darkness. D The municipal budget had a major surplus before installing the lights.

340

Read the sentence: 'The satellite detected surface thermal anomalies over the dormant volcano two months before small seismic tremors began rattling nearby valleys.' What can be inferred?

A Thermal changes can precede detectable seismic activity during early volcanic awakening. B Earthquakes cause dormant volcanoes to immediately cool down. C Satellites can stop volcanic eruptions by measuring surface heat. D Dormant volcanoes only erupt when seismic tremors are entirely absent.
