In Prefix Power, re- means again; reconsider means consider again with new evidence. Zuri reconsidered her opinion after reading a second source, and Eli reread the instructions to avoid errors. The prefix un- means not, and pre- means before, each shifting meaning clearly. Which word means “think again” based on its parts?

unaware

prevent

reconsider

prejudge

Explanation

This question tests ISEE Upper Level verbal reasoning skills, specifically inferring word meaning from roots, prefixes, and suffixes. Understanding word parts helps students systematically decode unfamiliar vocabulary. The passage explicitly defines 're-' as meaning 'again' and states that 'reconsider means consider again with new evidence,' with Zuri reconsidering her opinion as an example. Choice B 'reconsider' is correct because it combines the prefix 're-' (again) with 'consider' to mean 'think again,' directly answering the question's requirement. Choice A 'prejudge' uses 'pre-' meaning before; Choice C 'unaware' uses 'un-' meaning not; and Choice D 'prevent' also uses 'pre-' meaning before. To help students, encourage them to create word webs showing how the same prefix creates related meanings across different root words.

2

In Prefix Power, un- means not; unreliable means not reliable or trustworthy. The class found the website unreliable because facts changed between visits. The prefix re- means again, and pre- means before, but un- usually negates the base word. What does the prefix un- mean in the word unreliable?

again

not

over

before

Explanation

This question tests ISEE Upper Level verbal reasoning skills, specifically inferring word meaning from roots, prefixes, and suffixes. Understanding word parts enables systematic vocabulary analysis. The passage defines 'un-' as meaning 'not' and explains that 'unreliable means not reliable or trustworthy,' with the class finding a website unreliable as an example, noting that 'un-' usually negates the base word. Choice B 'not' is correct because it directly matches the definition given for the prefix 'un-' in 'unreliable,' showing how it negates the positive quality of being reliable. Choice A 'before' describes 'pre-'; Choice C 'again' describes 're-'; and Choice D 'over' is not mentioned in the passage. Students should practice identifying how 'un-' consistently negates positive qualities (unfair, unhappy, unreliable) to build confidence in decoding unfamiliar words.

3

In Prefix Power, un- means not; uncommon means not common in everyday experience. Leila felt uneasy before her speech, but she stayed calm and focused. The prefix re- means again, as in recheck, and pre- means before, as in pretest. Which word means “not equal” based on its parts?

unequal

pretest

predict

recheck

Explanation

This question tests ISEE Upper Level verbal reasoning skills, specifically inferring word meaning from roots, prefixes, and suffixes. Understanding word parts enables students to decode complex vocabulary systematically. The passage clearly defines 'un-' as meaning 'not,' using 'uncommon' as an example meaning 'not common,' and provides another example with 'uneasy' (not easy). Choice A 'unequal' is correct because it combines the prefix 'un-' (not) with 'equal' to mean 'not equal,' directly answering the question. Choice B 'pretest' uses 'pre-' meaning before; Choice C 'recheck' uses 're-' meaning again; and Choice D 'predict' also uses 'pre-' meaning before. To help students, encourage them to maintain a prefix journal where they record new words with familiar prefixes and practice breaking down words into their component parts.

4

During Prefix Power, pre- means before; preheat means heat before cooking begins. Aisha preplanned her schedule to avoid last-minute stress, and Diego previewed the chapter before class discussion. The prefix re- means again, as in rebuild, and un- means not, as in unequal. What does the prefix pre- mean in the word preheat?

again

before

after

not

Explanation

This question tests ISEE Upper Level verbal reasoning skills, specifically inferring word meaning from roots, prefixes, and suffixes. Understanding word parts helps students decode unfamiliar vocabulary efficiently. The passage explicitly states that 'pre-' means before, using 'preheat' as an example meaning 'heat before cooking begins,' and provides additional examples like 'preplanned' (planned before) and 'previewed' (viewed before). Choice B 'before' is correct because it directly matches the definition given in the passage for the prefix 'pre-' in 'preheat.' Choices A 'after' is the opposite of the correct meaning; Choice C 'again' describes the prefix 're-'; and Choice D 'not' describes the prefix 'un-'. Students should practice identifying prefixes in context and creating word families with the same prefix to strengthen their understanding of consistent prefix meanings.

5

Prefix Power explains re- means again; reorganize means organize again in a better order. Nia reorganized her binder after losing worksheets, and Arjun rechecked the table of contents. The prefix pre- means before, and un- means not, but only re- signals repetition. Identify the meaning of reorganize using its prefix and root.

not organize at all

organize against rules

organize again

organize before starting

Explanation

This question tests ISEE Upper Level verbal reasoning skills, specifically inferring word meaning from roots, prefixes, and suffixes. Understanding word parts helps students decode complex vocabulary systematically. The passage explicitly defines 're-' as meaning 'again' and states that 'reorganize means organize again in a better order,' with Nia reorganizing her binder as an example. Choice C 'organize again' is correct because it combines the prefix 're-' (again) with 'organize' to mean organizing something again, directly matching the definition provided. Choice A 'organize before starting' would use 'pre-'; Choice B 'not organize at all' would use 'un-'; and Choice D 'organize against rules' has no basis in the prefix meanings given. To help students, encourage them to notice how 're-' often implies improvement or correction when combined with action verbs like rebuild, rewrite, or reorganize.

6

Prefix Power shows pre- means before; pretest is a test given before instruction begins. Ms. Alvarez gave a pretest to measure prior knowledge, and students previewed the unit goals. The prefix re- means again, and un- means not, helping decode unfamiliar words. What does the prefix pre- mean in the word pretest?

again

not

across

before

Explanation

This question tests ISEE Upper Level verbal reasoning skills, specifically inferring word meaning from roots, prefixes, and suffixes. Understanding word parts enables efficient vocabulary decoding. The passage clearly defines 'pre-' as meaning 'before' and explains that 'pretest is a test given before instruction begins,' with Ms. Alvarez giving a pretest to measure prior knowledge as an example. Choice A 'before' is correct because it directly matches the definition provided for the prefix 'pre-' in 'pretest,' indicating something that occurs before the main event. Choice B 'not' describes 'un-'; Choice C 'again' describes 're-'; and Choice D 'across' is not mentioned in the passage. Students should practice identifying 'pre-' in academic contexts where timing and sequence matter, such as preview, prepare, and predict.

7

In a Prefix Power lesson, re- means again; rewrite means write again. Mira reread her notes before the quiz, and Jamal replayed the recording to catch details. Teachers said un- means not, so unfair means not fair, and pre- means before, so preview means view beforehand. Which word means “to do again” based on its parts?

preview

prevent

unfair

rewrite

Explanation

This question tests ISEE Upper Level verbal reasoning skills, specifically inferring word meaning from roots, prefixes, and suffixes. Understanding word parts helps break down complex words systematically. In the passage, the prefix 're-' is explicitly defined as meaning 'again,' as demonstrated in 'reread' (read again) and 'replayed' (played again). Choice C 'rewrite' is correct because it uses the prefix 're-' combined with 'write' to mean 'write again,' directly matching the question's requirement for a word meaning 'to do again.' Choice A 'preview' is incorrect because 'pre-' means before, not again; Choice B 'unfair' uses 'un-' meaning not; and Choice D 'prevent' also uses 'pre-' meaning before. To help students master this skill, encourage them to create prefix flashcards and practice identifying the same prefix across multiple words to reinforce pattern recognition.

8

In Prefix Power, pre- means before; prewrite means write ideas before drafting sentences. Sofia prewrote an outline, and Omar previewed the article to spot key terms. The prefix un- means not, and re- means again, helping readers infer meanings quickly. Identify the meaning of prewrite using its prefix and root.

write under pressure

write again

write before drafting

not write at all

Explanation

This question tests ISEE Upper Level verbal reasoning skills, specifically inferring word meaning from roots, prefixes, and suffixes. Understanding word parts helps students decode complex vocabulary efficiently. The passage explicitly defines 'pre-' as meaning 'before' and states that 'prewrite means write ideas before drafting sentences,' with Sofia prewriting an outline as an example. Choice B 'write before drafting' is correct because it accurately reflects the prefix 'pre-' (before) combined with 'write' to mean writing that occurs before the main drafting process. Choice A 'write again' would use the prefix 're-'; Choice C 'not write at all' would use 'un-'; and Choice D 'write under pressure' has no basis in the prefix meanings provided. To help students master this skill, encourage them to practice breaking down academic vocabulary into prefixes and roots, especially terms they encounter in writing instruction.

9

Prefix Power teaches un- means not; unplug means not plugged in anymore. Mateo unplugged the charger to save energy, and Hana untied the knot to reuse the ribbon. The prefix re- means again, and pre- means before, but un- often signals reversal or negation. What does the prefix un- mean in the word unplug?

together

not

again

before

Explanation

This question tests ISEE Upper Level verbal reasoning skills, specifically inferring word meaning from roots, prefixes, and suffixes. Understanding word parts enables systematic vocabulary analysis. The passage defines 'un-' as meaning 'not' and explains that 'unplug means not plugged in anymore,' with Mateo unplugging a charger as an example, and notes that 'un-' often signals reversal or negation. Choice C 'not' is correct because it directly matches the definition given for the prefix 'un-' in 'unplug,' indicating the negation or reversal of being plugged in. Choice A 'again' describes 're-'; Choice B 'before' describes 'pre-'; and Choice D 'together' is not mentioned in the passage. Students should practice identifying how 'un-' can both negate (unhappy = not happy) and reverse actions (untie = reverse of tie) to fully understand this versatile prefix.

10

Prefix Power explains that re- means again; rebuild means build again after damage. Chen rechecked his answers to reduce careless mistakes, and Priya repainted the fence after a storm. The prefix pre- means before, and un- means not, changing meaning in predictable ways. What does the prefix re- mean in the word rebuild?

again

before

under

not

Explanation

This question tests ISEE Upper Level verbal reasoning skills, specifically inferring word meaning from roots, prefixes, and suffixes. Understanding word parts helps students systematically analyze unfamiliar vocabulary. The passage explicitly defines 're-' as meaning 'again,' using 'rebuild' as the primary example meaning 'build again after damage,' and provides supporting examples like 'rechecked' (checked again) and 'repainted' (painted again). Choice C 'again' is correct because it directly matches the definition provided in the passage for the prefix 're-' in 'rebuild.' Choice A 'before' describes 'pre-'; Choice B 'not' describes 'un-'; and Choice D 'under' is not mentioned in the passage. Students should practice identifying the same prefix across multiple words and creating their own examples to reinforce understanding of consistent prefix meanings.
