Question

The writer wants to conclude the passage by restating its main idea. Which choice best accomplishes this goal? A) NO CHANGE B) scientists will adjust the nutrients added to the water to create produce with a better taste. C) the savings in water alone make hydroponics worthy of strong consideration. D) experts predict that there may even be a world war related to the use of water.

Short answer

Choice C ("the savings in water alone make hydroponics worthy of strong consideration") is the best option to conclude the passage by restating its main idea, as it highlights the importance of water savings and the benefits of hydroponics.

Step-by-step solution

Eliminate Irrelevant Choices

In this step, eliminate choices that are clearly unrelated to hydroponics and water usage or do not restate the main idea. - Choice A: NO CHANGE - Choice B: Scientists will adjust the nutrients added to the water to create produce with a better taste - Choice C: The savings in water alone make hydroponics worthy of strong consideration - Choice D: Experts predict that there may even be a world war related to the use of water Choice B focuses on the taste of the produce and the nutrients added, not on water usage, so we can eliminate it. Furthermore, choice D is too extreme and doesn't provide a summary of the main idea of the passage, so we can eliminate it as well.

Compare the Remaining Choices

Compare the remaining choices (A and C) to determine which one restates the main idea of the passage more effectively. - Choice A: NO CHANGE - Choice C: The savings in water alone make hydroponics worthy of strong consideration Since choice A is "NO CHANGE," assume that the passage already concludes with a restatement of the main idea. The only other remaining choice, choice C, explicitly mentions water savings and hydroponics, which fits well with water usage and hydroponics.

Choose the Best Option

Based on the analysis, choice C ("the savings in water alone make hydroponics worthy of strong consideration") is the best option to conclude the passage by restating its main idea, as it highlights the importance of water savings and the benefits of hydroponics.

Key concepts

SAT Preparation

Preparing for the SAT is a critical step in a student's educational journey, and it involves more than just learning the test material. It encompasses understanding the format of the test, the types of questions you will face, and the skills needed to succeed.

For sections like critical reading, ensure you're familiar with different kinds of passages and the questions that typically follow. Practice with sample questions, full-length practice tests, and time yourself to mimic actual test conditions. Additionally, develop a study schedule that allows regular review sessions, and use resources such as study guides and online platforms that offer detailed explanations and test-taking strategies.

Critical Reading

Critical reading on the SAT requires careful analysis of passages to understand their main ideas, themes, and structures. It's crucial to read actively, taking notes if necessary, and to approach each passage with a clear mind, looking out for author's arguments, supporting evidence, and the use of language and tone.

To improve your critical reading skills, practice by reading a variety of materials such as articles, novels, and scientific reports. Learn to identify thesis statements, summarize paragraphs, and infer meanings. Questions that ask you to identify the main idea, as seen in the hydroponics exercise, are common and require a strong grasp of these skills.

Test-taking Strategies

Effective test-taking strategies can dramatically improve your SAT scores. Start by reading the questions carefully before considering the answer choices. Eliminate blatantly wrong answers to improve your odds even if you have to guess. Time management is essential; allocate your time to questions based on their difficulty and your strengths.

Always review your answers if time permits, but first, ensure you've answered every question since there is no penalty for guessing on the SAT. In the context of the presented hydroponics exercise, step-by-step elimination is a key strategy to narrow down the best choice that recaps the main point of the passage.

Educational Passage Analysis

Analyzing educational passages, like those about hydroponics, involves understanding and interpreting data or arguments presented within the text. Look out for the author's purpose, the structure of the arguments, and any implications or conclusions drawn. In the SAT context, you will not only summarize what is directly stated but also what can be inferred.

Applying this skill in practice involves dissecting passages into their fundamental ideas, comparing and contrasting viewpoints, and evaluating the effectiveness of the author's message. The task of concluding a passage with its main idea assesses your ability to synthesize and distill information critically.
