The following text discusses quantum computing.
Quantum computers process information fundamentally differently than classical computers. While traditional bits exist as 0 or 1, quantum bits (qubits) can exist in multiple states simultaneously through superposition. This property enables quantum computers to explore many solutions in parallel. However, qubits are extremely fragile, requiring temperatures near absolute zero and isolation from electromagnetic interference.
What is the primary purpose of the text?
To argue for increased funding of quantum research
To compare different types of quantum computers
To explain quantum computing's unique properties and challenges
To predict when quantum computers will replace classical ones
Correct Answer: C
Choice C is the best answer. The text explains unique properties (superposition, parallel processing) and challenges (fragility, extreme cold requirements).
- Evidence: The text explains properties: "superposition," "explore many solutions in parallel." It explains challenges: "extremely fragile," "temperatures near absolute zero."
- Reasoning: The passage provides a balanced overview of the technology's potential and its current limitations.
- Conclusion: The purpose is to explain properties and challenges.
💡 Strategy: Summarize the two halves: The Cool Stuff (superposition) + The Hard Stuff (fragility).
Choice A is incorrect because funding isn't discussed. Choice B is incorrect because quantum types aren't compared. Choice D is incorrect because no predictions are made.
