(1 point)
① a is reliable; b is reliable; c is unreliable
① a is unreliable; b is unreliable; c is reliable
□ a is reliable; b is unreliable; c is reliable
□ a is reliable; b is unreliable; c is reliable

Explanation:

• Sentence A: Describing opal field environments as harsh is a factual, general observation supported by historical context, so it is reliable.
• Sentence B: Using the absolute term "None" is an overgeneralization—we cannot confirm every single pioneer disliked summer, so it is unreliable.
• Sentence C: Building underground homes to adapt to extreme opal field climates is a well-documented historical adaptation, so it is reliable.

Answer:

1. A is reliable; B is unreliable; C is reliable
