Section ARead this paragraph and answer the questions. Australia sells 10,000 tonnes of uranium for considerable profit each year. This produces as much energy as Australia consumes, but with less than 10% of the carbon dioxide emissions of coal-fired power plants. Investigations into the nuclear industry have concluded that uranium as a power source is not economically feasible for Australia. Unlike coal, which can be used to generate power with little processing, nuclear power plants cannot simply be fuelled with uranium ore. The nuclear fuel cycle begins when mined uranium ore is converted to yellowcake, which contains about 90% uranium oxides. This is the only phase of the nuclear fuel cycle that is established in Australia. Fill in the gap with ONE WORD from the paragraph. 1. Australia sells enough uranium to produce the amount of energy it Answer Question 1[input] yearly.

Question

BlackTom AI · Accepted Answer

The sentence in the paragraph reads “This produces as much energy as Australia consumes...,” so the missing word is the exact one used there.

1. Identify and explain the relevant knowledge points and concepts
- Reading comprehension and exact-word recall: the task requires selecting ONE WORD from the paragraph that completes the sentence logically and grammatically. Key concept: find the sentence in the text that expresses the same idea as the gap.

2. Show the complete reasoning process step by step
- Scan the paragraph for the clause about energy produced versus energy used by Australia.
- Locate: “This produces as much energy as Australia consumes, but with less than 10% ...”
- Map the question sentence to the located clause: “Australia sells enough uranium to produce the amount of energy it ____ yearly.”
- The word in the paragraph that fills this blank is “consumes.”

3. For calculations, show all intermediate steps
- No numerical calculation is required. The step is textual extraction: identify the corresponding sentence and copy the single word used there (“consumes”).

4. Explain WHY the correct answer is correct
- Grammatically, “it consumes yearly” correctly describes how much energy Australia uses in a year. Semantically, the paragraph explicitly states that the uranium sold produces “as much energy as Australia consumes,” so “consumes” is the precise word that completes the question sentence and preserves meaning.

5. For multiple choice: briefly explain why other options are incorrect
- Possible alternative words like “uses” or “needs” are synonyms but are not the exact word appearing in the paragraph. The instruction requires ONE WORD from the paragraph, so only “consumes” is acceptable. Words like “exports” or “sells” would contradict the meaning.

6. Conclusion confirming the final answer
- Therefore, the correct word to fill the gap is “consumes,” which matches the provided answer.
