Chapter 1: Problem 21

Which additional information, if presented in figure 2, would be most useful in evaluating the statement in lines 13鈥�15 (鈥淲hile...system鈥�)? A) The total number of GPS devices sold B) The number of individuals in each industry using GPS devices C) The percentage of the industry that relies on the GPS devices D) The amount of revenue in dollars for each industry

Short Answer

Expert verified
The best option to evaluate the statement in lines 13-15 would be C) The percentage of the industry that relies on the GPS devices, as it directly addresses the extent of reliance on GPS devices in various industries.

Step by step solution

01

Understand the statement and context.

Read and understand the statement given in lines 13-15: 鈥淲hile...system鈥�. The statement talks about the increased use and reliance on GPS devices in various industries as the system improves.
02

Evaluate each choice.

Consider each answer choice and determine which one is most useful in evaluating the statement: A) The total number of GPS devices sold: This provides an overall understanding of the GPS market but does not directly address the reliance of industries on GPS devices. B) The number of individuals in each industry using GPS devices: Knowing the total number of users in each industry helps understand the impact on each industry, but it does not show the extent of reliance on GPS devices. C) The percentage of the industry that relies on the GPS devices: This directly addresses the extent of reliance on GPS devices in each industry, thus providing the necessary information to evaluate the statement. D) The amount of revenue in dollars for each industry: While this gives an overview of the financial impact of GPS devices on each industry, it does not necessarily reflect the level of reliance or usage within the industry.
03

Choose the best option.

Based on the evaluation in Step 2, the most useful information to evaluate the statement in lines 13-15 would be choice C - The percentage of the industry that relies on the GPS devices. This directly addresses the extent of reliance on GPS devices in various industries and provides the best information to evaluate the statement.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Evaluating Statements
Evaluating statements is a quintessential skill in SAT problem-solving. It involves critically analyzing a claim or a statement to ascertain its validity or to understand the concept it presents.

When faced with a problem that asks to evaluate statements, students should first identify what information is required to support or refute the statement at hand. For instance, in the GPS industry example, understanding the reliance level is crucial. The correct approach includes interpreting the given data and assessing which additional facts could provide insight into how industries depend on GPS devices. It's not just about what the numbers say; it's about the story they tell.

Practical Tips:
  • Focus on the contextual information relevant to the statement.
  • Ignore extraneous data that doesn鈥檛 contribute to the evaluation process.
  • Consider how each piece of information would directly affect the interpretation of the statement.
Critical Reading
Critical reading is a vital component of SAT success, particularly when it comes to understanding complex passages and questions. It involves reading with a discerning eye, questioning assumptions, and identifying the underlying logic or argument.

In the context of the SAT, critical reading means not taking the text at face value but rather analyzing its building blocks. For the GPS problem question, critical reading is utilized to grasp the significance behind the reliance on GPS devices within different industries. It's key to focus on what the question is actually asking, not what it appears to be asking at first glance.

Proven Strategies:
  • Note keywords in the passage that hint at the main idea or theme.
  • Analyze the structure of the argument presented.
  • Understand the implications of specific choices given in a problem.
Data Interpretation
Data interpretation tests the student鈥檚 ability to process and analyze quantitative information, a skill pivotal for SAT problem-solving. It requires students to make sense of numbers, graphs, and tables to answer questions effectively.

Within the example of the SAT question concerning GPS device usage, data interpretation would involve looking at figures and statistics鈥攐r additional data if it were provided鈥攖o extrapolate the extent of GPS reliance. Students should compare the given options in a logical manner to derive the most explanatory way of addressing the statement.

Critical Points:
  • Examine graphical data as it can often communicate more efficiently than words.
  • Read charts and tables with an understanding of what each axis represents.
  • Identify trends or patterns in the data that are relevant to the problem.
SAT Test Preparation
Effective SAT test preparation encompasses more than just knowledge; it鈥檚 about developing the right skill set to tackle the different kinds of questions that will appear on the exam. Strategy is as important as study when it comes to the SAT.

In terms of problem-solving, this includes becoming proficient in the skills previously mentioned: evaluating statements, critical reading, and data interpretation. Committing to regular practice using sample SAT questions, like the GPS devices question, can substantially improve these skills. Also, understanding the format of the test and the types of questions asked can help students manage their time more effectively during the actual exam.

Key Preparation Tips:
  • Practice with a variety of SAT problems to become comfortable with the question formats.
  • Build a study schedule that allows for consistent review and practice.
  • Learn test-taking strategies, such as process of elimination and time management.
