read the sentence taken from an argumentative essay on space exploration. space exploration would cost a ton of money, but i would probably learn a lot of new things, so its probably worth it. which of the following is the best revision of this sentence? space exploration might not be the best use of money, but i think it would be really cool. space exploration probably isnt worth the high price, but who knows what well find out there. space exploration is quite pricey and dangerous, but it is also very interesting. space exploration is extremely expensive, but the knowledge gained is worth the price.
Answer
Brief Explanations:
The original sentence balances the high - cost aspect of space exploration with the value of new knowledge gained. The best revision should maintain this balance. The first option only mentions it being cool, the second is more negative about its worth, the third adds danger which isn't in the original, and the fourth option clearly restates the cost - benefit balance as in the original.
Answer:
Space exploration is extremely expensive, but the knowledge gained is worth the price.
