This question tests ISEE Middle Level verbal reasoning skills, specifically the use of prefixes, suffixes, or roots to infer word meaning. Understanding word parts like prefixes, suffixes, and roots helps in deducing meanings. For example, 'prehistoric' combines 'pre-' (before) and 'historic' (relating to history). In this passage, the word prehistoric is used to convey a time before written records based on context clues such as 'early humans lived long before written records'. Choice B is correct because the prefix 'pre-' means 'before,' accurately reflecting that prehistoric refers to the time before recorded history. Choice A is incorrect because it reverses the meaning of the prefix, a common mistake when students confuse prefixes like 'pre-' and 'post-'. To help students: Create prefix charts showing 'pre-' (before), 'post-' (after), 'anti-' (against), and 'co-' (together), and practice identifying these prefixes in various academic contexts.

This question tests ISEE Middle Level verbal reasoning skills, specifically the use of prefixes, suffixes, or roots to infer word meaning. Understanding word parts like prefixes, suffixes, and roots helps in deducing meanings. For example, 'deforestation' combines 'de-' (removal, reversal), 'forest', and '-ation' (process or action). In this passage, the word deforestation is used to convey the removal of trees based on context clues such as 'removes many trees at once' and 'leaving animals without homes'. Choice C is correct because it accurately reflects the word's meaning as cutting down many trees, which aligns with the prefix 'de-' indicating removal and the context describing environmental damage. Choice A is incorrect because it suggests the opposite action (planting rather than removing), a common mistake when students confuse 'de-' with 're-' prefixes. To help students: Create exercises comparing 'de-' words (deforestation, dehydration) with 're-' words (reforestation, rehydration) to clarify their opposite meanings.

This question tests ISEE Middle Level verbal reasoning skills, specifically the use of prefixes, suffixes, or roots to infer word meaning. Understanding word parts like prefixes, suffixes, and roots helps in deducing meanings. For example, 'recycle' combines 're-' (again) and 'cycle' (circular process). In this passage, the word recycle is used to convey using materials again based on context clues such as 'using materials again instead of throwing them away'. Choice A is correct because the prefix 're-' means 'again,' accurately reflecting that recycling involves processing materials to use them again. Choice B is incorrect because it confuses 're-' with 'sub-' (under), a common mistake when students don't systematically learn prefix meanings. To help students: Teach common 're-' words (reuse, rebuild, return) to reinforce the 'again' meaning, and practice identifying this prefix across different subject areas.
