   Reading Passage

   Maya stared at the erratic blue neon light on her workbench, her eyes burning from hours of scrutiny. Outside, a gentle Bay Area rain tapped rhythmically against the garage window, but inside, the silence felt deafening. Her autonomous rover, named Artemis, was supposed to navigate the labyrinthine maze on her floor and trigger a micro-switch at the exit. Instead, every time Artemis reached the second juncture, the right motor seized up, sending the chassis spinning uselessly in circles.

   Her older brother, Julian, leaned against the doorframe, sipping tea from a chipped mug. "Still chasing ghosts in the code?" he asked softly. "The regional showcase starts in nine hours, Maya. Sometimes discretion is the better part of valor. You could submit the manual override program."

   Maya gritted her teeth, adjusting her wire-strippers. The manual override felt like entering a marathon in a golf cart; it lacked the elegant autonomy she had spent four months engineering. "The logic in the navigation array isn't flawed, Julian," she insisted, her voice tight but resolute. "It's an edge case. The infrared sensor is interpreting the reflective sheen of the floor lacquer as a physical wall."

   She pulled up the script on her monitor, scrolling past hundreds of lines of python code until her cursor hovered over the sensor calibration loop. With surgical precision, she adjusted the threshold parameter from 0.85 to 0.62 and recompiled the firmware.

   She set Artemis back at the starting line. The rover hummed to life, wheels gripping the composite board. It sped forward, paused at the dreaded second turn, adjusted its course by three degrees, and smoothly glided past the lacquer flare. Maya let out a breath she hadn’t realized she was holding as Artemis clicked the final target switch.

   1.Which sentence best states a central theme of the narrative?

   A.Success in complex endeavors often requires persistent problem-solving rather than taking shortcuts.B.Modern technological advancements have made traditional engineering methods obsolete.C.Family members usually offer unhelpful advice when facing strict deadlines.D.Precision tools are more critical to success than logical reasoning.

6. Part 2 · Informational Text

   Reading Passage

   For decades, classical silicon microprocessors have relied on copper interconnects to shuttle electrical signals between logic gates. However, as computational demands exponentially surge alongside artificial intelligence models, these traditional copper traces have encountered a severe physical barrier known as resistive heating. As microchips cram billions more transistors into nanometer-scale footprints, electrical resistance generates excessive heat and throttles transmission speeds, creating an unsustainable bottleneck for modern supercomputers.

   To bypass this fundamental bottleneck, photonics engineers are pioneering microfluidic and optical interconnects that utilize light—specifically photons—rather than electrons to transfer data. Known as silicon photonics, this emerging technology integrates microscopic lasers, optical waveguides, and photodetectors directly onto silicon substrates. Photons travel through silicon waveguides at optical speeds without incurring resistive losses, enabling data transfer rates upwards of one terabit per second per optical channel while reducing power consumption by over sixty percent.

   Nevertheless, transitioning from electronic to optical architectures presents staggering manufacturing hurdles. Photonic components require sub-nanometer fabrication precision; even a microscopic misalignment of a nanophotonic waveguide can scatter light particles, rendering the optical signal useless. Additionally, managing thermal fluctuations within datacenter servers remains critical, as subtle temperature shifts alter the refractive index of silicon waveguides and disrupt delicate optical frequencies.

   Despite these formidable manufacturing challenges, tech consortia across Northern California and global research institutes are pouring billions into photonic integration. As quantum computing and high-performance neural networks mature, optical interconnects will inevitably displace copper wiring. Silicon photonics represents not merely an incremental upgrade, but a monumental paradigm shift in processing architecture—paving the way for next-generation computing that operates literally at the speed of light.

   6.Which statement best summarizes the central idea of the passage?

   A.Classical silicon microprocessors are completely ineffective for basic household computing needs.B.Supercomputers are failing worldwide due to the unavoidable costs of copper manufacturing.C.Silicon photonics uses light signals to overcome copper wire limitations, offering faster computing despite production hurdles.D.Managing server room temperatures is the single most important factor in computer processing speed.

    Reading Passage

    The midnight lamp reflects upon the board, A tangled path where silent currents run; No triumph won by sharp and sudden sword, But patience weaving threads until they’re one.

One single line restored, the gears align— The quiet victory of tested design.
