"Internet comes to the rescue: Solving a 1st grader's homework puzzle"

A mother in the UK turned to Facebook for help with her first grader's homework assignment, which asked to identify the odd word out among "friend, toothbrush, silver, desk, and egg." Various responses included toothbrush having two syllables, egg being the only edible item, and friend being a person rather than an object. The correct answer, according to the teacher, was silver, as it can be both an adjective and a noun. The exercise sparked different theories and discussions among parents and social media users.
