Answer:In definitional claims, child labor refers to the employment of children in work that is harmful to their physical, mental, or moral development. Here's a breakdown of the key aspects: - Employment: It involves children being engaged in work activities, whether paid or unpaid.- Harm: The work must be detrimental to the child's well-being. This can include physical risks, psychological stress, exploitation, or interference with education and development.- Development: It focuses on the negative impact on the child's overall growth, including their physical health, mental well-being, cognitive abilities, and social skills. Important Considerations: - Age: The definition of "child" varies by country and context, but generally refers to individuals under a certain age (often 15 or 18).- Context: The definition of "harmful" is also context-dependent. Work considered safe and appropriate for adults may be harmful to children due to their developmental stage and vulnerability.- Legality: Most countries have laws prohibiting child labor or regulating it to ensure children's safety and well-being.
Answer:The correct answer is:A. They provide specific measurements and observations that clearly show how the Earth’s size was calculated.Simon Singh's explanation of Eratosthenes’ experiment enhances the reader’s understanding by detailing the measurements and observations used to estimate the Earth's circumference. This includes information about the angle of the Sun's rays in two different locations and the distance between them, which were key to Eratosthenes' calculations.
Answer:The best answer is A. They provide specific measurements and observations that clearly show how the Earth’s size was calculated.Singh's explanation likely highlights the scientific approach and key calculations Eratosthenes used—such as measuring the angles of the Sun's shadow in two cities (Syene and Alexandria) and applying geometry. These details directly contribute to the reader's understanding of how Eratosthenes estimated the Earth's circumference. Let me know if you'd like more context!
