MathProblem-Solving and Data AnalysisHard
A store raises the price of a jacket by 20%. Later, it lowers the new price by 20%. The final price is what percent of the original price?
A80%
B96%Correct
C100%The trap
D104%
Check with $100: $100→then$120→then$96
Turn each change into a multiplier.
Up 20% means × 1.20. Down 20% means × 0.80.
Apply them in order.
1.20 × 0.80 = 0.96
Read the answer.
The final price is 96% of the original. That’s B.
Why not 100%?
The 20% cut is taken from the higher price, so it removes more than the 20% increase added.

Yes. In the standard full-length tests, Module 2 of each section is the harder version if you get 60% or more of Module 1 right, and the easier version if you don’t. Challenge tests use the hardest material throughout.

Rhetorical Synthesis · Lesson 2
True notes, wrong goal
Every wrong answer in a Rhetorical Synthesis question is a good sentence. It is accurate, it uses the notes, and it is often the right answer to a different question. The test writers build many distractors by answering nearby goals.
So a useful habit is to name the job each choice does. This one specifies when. This one describes how the panel is made. This one states the result but not the reason. Then compare that job with the goal in the question. Only one will match it exactly.
The hardest distractors share the right topic but do the wrong task. If the goal is to explain an advantage of a new material, a choice that describes the material is on topic, yet it explains nothing. If the goal is to state the aim of a study, a choice that reports the study's results is on topic, yet a result is not an aim.
Watch the small words in the goal: difference versus similarity, why versus when, aim versus findings, and whether the audience is unfamiliar. One word in the goal often eliminates two choices.
Worked example Medium
While researching a topic, a student has taken the following notes:
- Katherine Johnson was a mathematician at NASA.
- She calculated flight paths for early US spaceflights.
- In 1962, astronaut John Glenn asked her to check the computer calculations for his orbital flight.
- She was awarded the Presidential Medal of Freedom in 2015.
- Her work was featured in the 2016 film Hidden Figures.
The student wants to introduce Katherine Johnson to an audience unfamiliar with her. Which choice most effectively uses relevant information from the notes to accomplish this goal?
- Katherine Johnson, a NASA mathematician, calculated flight paths for early US spaceflights.Answer
- In 1962, John Glenn asked Johnson to check the computer calculations for his orbital flight.
- Johnson was awarded the Presidential Medal of Freedom in 2015.
- The 2016 film Hidden Figures featured Johnson's work.
How to solve it
- The key word is unfamiliar. The reader has never heard of Johnson, so the sentence must say who she is.
- Name the job of each choice. Three of them report a story, an award or a film about her, using only her last name. Each one assumes the reader already knows who Johnson is.
- Katherine Johnson, a NASA mathematician, calculated flight paths for early US spaceflights gives her full name, her job and what she did.
Why each choice is right or wrong
- A. Correct. The sentence identifies Johnson with her full name and her role, then says what her work was, which is exactly what an unfamiliar reader needs.
- B. Incorrect. This is an interesting detail, but it uses only her last name and never says who she is or what her job was.
- C. Incorrect. The award is impressive, but a reader who doesn't know Johnson still won't learn who she is or what she did.
- D. Incorrect. This sentence mentions Johnson's work without saying what that work was or who Johnson is, so it assumes familiarity.
Worked example Hard
While researching a topic, a student has taken the following notes:
- In 2023, materials scientist Ana Lindqvist developed a new type of insulation panel.
- The panel is made from compressed hemp fibers held together by a lime-based binder.
- In tests, the panel insulated as well as a standard fiberglass panel of the same thickness.
- Unlike fiberglass, the hemp panel absorbs moisture from humid air and releases it when the air is dry.
- This moisture control can help prevent mold from growing inside walls.
The student wants to explain an advantage of Lindqvist's panel over fiberglass. Which choice most effectively uses relevant information from the notes to accomplish this goal?
- Lindqvist's panel is made from compressed hemp fibers held together by a lime-based binder.
- In tests, Lindqvist's hemp panel insulated as well as a fiberglass panel of the same thickness.
- Unlike fiberglass, Lindqvist's hemp panel absorbs and releases moisture from the air, which can help prevent mold inside walls.Answer
- In 2023, materials scientist Ana Lindqvist developed a new type of insulation panel.
How to solve it
- The task is to explain an advantage, and the comparison is with fiberglass. The sentence needs something the hemp panel does better than fiberglass.
- Name each choice's job. One describes what the panel is made of. One says the panel insulates as well as fiberglass: that is a tie, not an advantage. One specifies when the panel was developed.
- Unlike fiberglass, Lindqvist's hemp panel absorbs and releases moisture from the air, which can help prevent mold inside walls names a difference and says why it matters.
Why each choice is right or wrong
- A. Incorrect. This sentence is on topic, but it only describes the panel's materials. It never compares the panel with fiberglass or names a benefit.
- B. Incorrect. This is the tempting choice: it compares the panel with fiberglass and sounds positive. But as well as means the two perform the same, so it shows the panels are equal in insulation, not that the hemp panel has an advantage.
- C. Correct. The sentence names something the hemp panel does that fiberglass doesn't, and it explains the benefit: helping prevent mold.
- D. Incorrect. This sentence specifies who developed the panel and when. It gives no advantage.
