Directions (36-44): Read the following passage and answer the given questions. In the world of armed forces, dogs play an extraordinary role that goes far beyond companionship. They serve as trackers, guards, messengers, and protectors, often working in harsh terrains and unpredictable missions. Military dogs are essential for detecting hidden explosives, tracking infiltrators, and alerting troops to potential threats. Their sharp instincts, unmatched loyalty, and rigorous preparation make them indispensable partners in critical operations. They are not just supporting figures; they are front-line defenders. Far from being fillers in military structures, these brave animals are sentinels, standing watch when danger lurks and acting with courage when every second counts. Among these remarkable canines was Snowy, a spirited dog with a gleaming white coat that earned him his name. From the moment he arrived at the training center, his alert eyes and quick learning impressed everyone. Snowy was trained at a specialized military academy where he mastered complex commands, learned to detect explosives, and adapted to challenging terrains. He was conditioned to remain calm under pressure, respond to silent signals, and work seamlessly with his handler. His training was not merely about obedience; it was about building instincts, discipline, and trust. Once Snowy joined the unit at a remote border post, he quickly became a beloved member of the team. Soldiers admired his energy, while his handler relied on his sharp senses during night patrols. One freezing night, the camp lay quiet under a pale moonlight. The soldiers were resting after a long day when Snowy’s ears suddenly __________________. He sensed movement near the perimeter. Without hesitation, he barked sharply and ran toward the fence, alerting the guards. His timely reaction allowed the soldiers to spot and intercept a group trying to cross the border secretly. Snowy’s vigilance averted a potential threat, and that night, he truly embodied the role of a sentinel—watchful, fearless, and devoted. Beyond his operational duties, Snowy shared a deep emotional bond with the soldiers. He sensed when someone was anxious, resting his head gently on their knees, as if offering silent comfort. He celebrated victories with wagging enthusiasm and stood quietly beside those who missed home. Snowy was more than a military dog; he was a loyal friend, a trusted partner, and a hero in his own right. His story reflects the invaluable role dogs play in safeguarding lives and supporting those who protect the nation.
