The student has effectively based their TOK essay on one of the 35 prompts released by the IBO, specifically addressing "To what extent is certainty attainable?" They have presented three distinct objects, each linked to the prompt, and provided detailed commentary that adheres to the word limit. However, the student has not clearly established the real-life context for each object, particularly regarding the generic nature of the atom as a concept. Despite this, the student successfully explains how each object contributes to the exploration of the prompt and supports their arguments with sufficient evidence and clear references. Overall, the student has ensured that all information presented is relevant and contributes to the central theme of certainty.
