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.

Form, Structure, and Sense · Lesson 3
Modifiers that point at the right noun
A modifier is a word or phrase that describes something. When a sentence opens with a descriptive phrase followed by a comma, such as Completed in 1889, Walking through the forest or An expert in manuscripts, that phrase describes the subject of the main clause, which should come right after the comma.
If that noun isn't the thing being described, the modifier dangles. Walking through the forest, the fungi glowed says the fungi were walking.
To solve these questions, ask who or what the opening phrase describes: who was walking, what was completed, who is the expert. Then pick the choice that makes that exact noun the subject of the main clause.
A correct opener is not a fragment or an error. Seeking to measure the drift, the team installed sensors is correct, because the team is who was seeking. The phrase goes wrong when the subject of the main clause isn't the thing it describes.
Worked example Easy
Completed in 1889 for a world's fair in Paris, the tallest human-made structure in the world until 1930.
Which choice completes the text so that it conforms to the conventions of Standard English?
- the Eiffel Tower remainedAnswer
- engineers had made the Eiffel Tower
- Gustave Eiffel's company built what remained
- the height of the Eiffel Tower made it
How to solve it
- Ask what was completed in 1889. The Eiffel Tower was.
- So the main clause must begin with the Eiffel Tower.
- Only the Eiffel Tower remained makes the tower the subject of the main clause.
Why each choice is right or wrong
- A. Correct. The Eiffel Tower is what was completed in 1889, and it is the subject that follows the opening phrase.
- B. Incorrect. The subject after the comma is engineers, so the sentence says the engineers were completed in 1889.
- C. Incorrect. The subject after the comma is Gustave Eiffel's company, so the sentence says the company was completed in 1889.
- D. Incorrect. The subject after the comma is the height, so the sentence says the height, not the tower, was completed in 1889.
Worked example Medium
Having tracked Arctic terns with tiny tracking devices for more than a decade, that the birds' migration routes shift from year to year with the prevailing winds.
Which choice completes the text so that it conforms to the conventions of Standard English?
- the ecologist Mara Lind's conclusion was
- the ecologist Mara Lind concludedAnswer
- it was concluded by the ecologist Mara Lind
- the conclusion of the ecologist Mara Lind was
How to solve it
- Ask who tracked the terns. A person did: the ecologist Mara Lind.
- So the subject of the main clause must be the ecologist Mara Lind, not her conclusion.
- The ecologist Mara Lind concluded makes her the subject.
Why each choice is right or wrong
- A. Incorrect. Mara Lind's is a possessive, so the subject is conclusion. The sentence says the conclusion tracked the terns.
- B. Correct. The ecologist is the one who tracked the terns, and she is the subject that follows the opening phrase.
- C. Incorrect. The subject is it. Mara Lind appears only inside the phrase by the ecologist Mara Lind, so she isn't the subject, and the opening phrase has no one to describe.
- D. Incorrect. The subject is the conclusion, so the sentence says the conclusion tracked the terns.
