Question 1

1. Break con-fi-dent-ly; sound out each syllable and blend them to read the whole word (correct answer)
2. Break co-nfi-de-ntly; keep nf together and skip vowels to make it faster
3. Break conf-id-ent-ly; read conf like "cough," then guess the rest from the sentence
4. Do not break into syllables; say each letter name, then try to hear the word

Explanation: This question tests decoding unfamiliar multisyllabic words using letter-sound correspondences, syllabication, and morphology (CCSS.RF.4.3.a), specifically breaking words into syllables correctly. To decode 'confidently,' students should break it into syllables following standard patterns: con-fi-dent-ly, then sound out each syllable and blend them together. The word breaks down as: con-fi-dent-ly, following the VC/V pattern (con-fi) and adding the suffix -ly (in a manner of). Choice A is correct because it shows the proper syllable breaks (con-fi-dent-ly) following syllabication rules, keeping each syllable as a pronounceable unit that can be sounded out and blended. Choice B is incorrect because it breaks the word as 'co-nfi-de-ntly,' incorrectly keeping 'nf' together as a blend when they belong to different syllables (con-fi), violating the rule that syllables typically break between consonants. To help students decode unfamiliar multisyllabic words: Teach syllabication rules and patterns: VC/CV (rab-bit), V/CV (mu-sic), VC/V (cab-in), V/V (di-et), C-le (ta-ble). Emphasize that syllables usually break between consonants (con-fi, not co-nfi) unless they form a blend at the beginning of a syllable. Model think-aloud: 'I see the word confidently. I'll break it into syllables: con-fi-dent-ly. Each syllable has at least one vowel sound. Now I'll sound out each part: /con/ /fi/ /dent/ /ly/ and blend them together: confidently.' Watch for students who keep consonants together incorrectly or break within consonant blends.

Question 2

1. in-ter-na-tion-al (correct answer)
2. int-er-nat-ion-al
3. i-nter-na-tio-nal
4. inter-nation-al

Explanation: International breaks into five syllables: in, ter, na, tion, and al, matching answer A. Answer B is wrong because it splits the sounds at the wrong points, joining letters that do not belong together. Answer C is wrong because it starts with a single letter as its own syllable, which does not match how the word sounds. Answer D is wrong because it groups letters into chunks that are too large to be true syllables.

Question 3

1. Port means "write," so transportation means writing across.
2. Port means "carry," so transportation means carrying across. (correct answer)
3. Port means "look," so transportation means looking across.
4. Port means "talk," so transportation means talking across.

Explanation: The root port means "carry," so transportation is the act of carrying people or things from one place to another—just like a bus carries students to school. The choice saying port means "write" is wrong because writing has nothing to do with a bus moving people. The choice saying port means "look" is also wrong, since seeing something is not the same as moving it. The choice saying port means "talk" is wrong too, because talking does not carry anyone anywhere. Knowing that port means "carry" also helps you understand words like transport and portable.

Question 4

1. in-ter-na-tion-al (correct answer)
2. int-er-nat-ion-al
3. in-tern-at-io-nal
4. i-nter-na-tional

Explanation: The correct answer is A because international correctly breaks into the syllables in, ter, na, tion, and al. Choice B is wrong because it splits sounds in the wrong places, such as int and ion. Choice C is wrong because tern and io do not match how the word is actually pronounced. Choice D is wrong because i and nter break the first syllable incorrectly.

Question 5

1. port means carry, so transportation relates to carrying people or things from one place to another (correct answer)
2. port means door, so transportation relates to opening the way into another place or building
3. port means water, so transportation relates to floating across rivers and lakes to reach land
4. port means move, so transportation relates to moving quickly whenever you feel like hurrying somewhere

Explanation: The root port means carry, so transportation relates to carrying people or things from one place to another. That is why we use cars, buses, and trains to move things and people. The choice that says port means door mixes it up with words like portal, but that is a different word part and does not fit here. The choice that says port means water sounds close because a harbor is called a port, but that meaning comes from a different root, not the port in transportation. The choice that says port means move seems reasonable because transportation does involve movement, but the root itself means carry, not move. Only the meaning carry unlocks the whole word: trans (across) plus port (carry) means carrying something across a distance.

Question 6

1. Break the word into syllables (ex-tra-or-di-nar-y), sound out each part, then blend them together. (correct answer)
2. Read the first syllable ex- clearly, then say the word that first pops into your head and move on.
3. Split the word into ext-ra-ord-inary, sound out those chunks carefully, then blend them all together.
4. Say each letter name in order (e-x-t-r-a-o-r-d-i-n-a-r-y), then join those names into the word.

Explanation: The best way to read a long word is to break it into real syllables (ex-tra-or-di-nar-y), sound out each part, and blend them together. Reading only ex- and then saying the first word that pops into your head is a guess that ignores the rest of the letters, so it often gives the wrong word. Splitting the word as ext-ra-ord-inary breaks it at the wrong places, so even careful blending will not match how the word really sounds. Saying each letter name (e-x-t-r-a-o-r-d-i-n-a-r-y) gives you letter names, not sounds, so joining names like "ee-ex-tee" will never build the spoken word. Only real syllables, sounded out and blended, help you decode extraordinary.

Question 7

1. Re- means again, so rearrangement means arranging again. (correct answer)
2. Re- means not, so rearrangement means not arranging.
3. Re- means before, so rearrangement means arranging before.
4. Re- means back, so rearrangement means arranging backward.

Explanation: The prefix re- means again, so rearrangement means arranging the desks again, or in a new way. The choice that says re- means not is wrong, because that negative meaning belongs to prefixes like un- or dis-, not re-. The choice that says re- means before is wrong, because that meaning belongs to the prefix pre-. The choice that says re- means back sounds close, since re- can suggest returning, but rearrange does not mean arranging backward. Only 'again' fits how the word is used in this sentence.

Question 8

1. -ment means "in a certain way," so encouragement means done in an encouraging way.
2. -ment means "action or result," so encouragement means the act of encouraging. (correct answer)
3. -ment means "full of," so encouragement means full of courage.
4. -ment means "a person who," so encouragement means a person who encourages.

Explanation: The suffix -ment turns a verb into a noun that names an action or result, so encouragement means the act of encouraging someone. The choice saying it means "in a certain way" describes what the suffix -ly does, and it also makes an adverb, not a noun. The choice saying it means "full of" describes the suffix -ful, so it does not fit -ment. The choice saying it means "a person who" describes the suffix -er or -or, which name people, not actions. Only "action or result" correctly explains what -ment does to encourage.

Question 9

1. Break un-pre-dict-a-ble; un- means not; predict means tell ahead; -able means can be (correct answer)
2. Break unp-red-icta-ble; unp- means before; redict means read again; -able means very much
3. Break un-pred-ict-able; un- means not; pred means storm; -ict means weather; -able means can be
4. Break re-pred-ict-able; re- means again; predict means tell ahead; -able means can be

Explanation: The best breakdown splits the word into un-pre-dict-a-ble and matches each part to its real meaning: un- means not, predict means to tell ahead, and -able means can be. Together, unpredictable means "cannot be told ahead," which fits a storm you can't guess. One choice invents word parts like unp- and redict and gives them made-up meanings, so the breakdown falls apart. Another keeps some real parts but pretends pred means storm and -ict means weather; those aren't real word parts, and it just borrows the sentence's topic instead of truly decoding. The last choice breaks off re- at the front, but the word begins with un-, not re-, so "re-predict-able" is not this word. Only the first breakdown uses the true prefix, root, and suffix.

Question 10

1. un-for-tu-nate-ly (correct answer)
2. unf-or-tun-ate-ly
3. u-nfor-tun-at-ely
4. un-for-tunat-ely

Explanation: The word unfortunately breaks into five syllables: un, for, tu, nate, and ly, matching answer A. Answer B is wrong because it splits the sounds in the wrong places, like breaking off just an f. Answer C is wrong because it starts with a single letter as its own syllable, which does not match how the word sounds. Answer D is wrong because it joins nat and at together instead of keeping nate as its own syllable.

Question 11

1. re-spon-si-bil-i-ty; read each syllable, then blend them, noticing that -ity is a suffix (correct answer)
2. res-pons-ibi-lity; split after the first blend, then read the last part as one long chunk
3. resp-on-sib-il-ity; break between the two s letters and sound out each piece quickly
4. re-sponsi-bility; keep sponsi together as the root and add the ending -bility to it

Explanation: The best breakdown is re-spon-si-bil-i-ty, because it splits the word into real syllables you can read one at a time and then blend together. It also points out that -ity is a suffix, which combines phonics with word parts to help you say the whole word. The choice that reads res-pons-ibi-lity is wrong because it groups letters that do not match syllable patterns, and treating the ending as one long chunk hides the beat of each syllable. The choice that reads resp-on-sib-il-ity is wrong because splitting between the two s letters cuts across sounds instead of following syllable breaks, so the pieces do not sound right. The choice that reads re-sponsi-bility is wrong because sponsi is not a real word part, and -bility is not the true suffix; the actual suffix is -ity. When you break a long word, look for syllable patterns and known word parts like -ity, then blend the syllables smoothly.

Question 12

1. pre- is the suffix because it comes at the beginning and means "before."
2. dict is the suffix because it comes in the middle and carries the main meaning.
3. -able is the suffix because it comes at the end and means "able to be." (correct answer)
4. predict is the suffix because it comes first and can stand alone as a word.

Explanation: A suffix is a word part added to the end of a word, and -able means "able to be," so predictable means able to be predicted. The part pre- also has a real meaning, "before," but it sits at the beginning, which makes it a prefix, not a suffix. The part dict carries the main meaning in the middle, so it is the root, not the suffix. And predict can stand alone as a word, which makes it the base word here, not the suffix. Only the ending -able fits what a suffix is: a part joined to the end of a base word to change its meaning.

Question 13

1. Look only at the first letter, ex, then guess the rest of the word from the sentence around it.
2. Break the word into syllables, ex-tra-or-di-na-ry, then blend the syllables together to say it. (correct answer)
3. Break the word into ext-raor-din-ary, then say the first chunk "ext" like the beginning of "exit."
4. Break the word into two big parts, extra and ordinary, then just say the second part out loud.

Explanation: The best strategy is to break the word into its real syllables, ex-tra-or-di-na-ry, and blend them smoothly together, because sounding out each part in order helps you read a long word correctly. Looking only at the first letters and guessing from the sentence skips most of the word, so you never really read it. Breaking it into ext-raor-din-ary uses the wrong syllable chunks, which makes the sounds come out wrong, like saying "ext" for "exit." Splitting it into extra and ordinary and only saying the second part leaves off the beginning, so you never say the whole word. Only blending all the real syllables lets you decode extraordinary the right way.

Question 14

1. mis- means "too much," so misunderstanding means understanding too much about something.
2. mis- means "wrong," so misunderstanding means understanding something in a wrong way. (correct answer)
3. mis- means "without," so misunderstanding means understanding without any help at all.
4. mis- means "fully," so misunderstanding means understanding something in a full way.

Explanation: The prefix mis- means "wrong" or "badly," so misunderstanding means understanding something in a wrong way. That matches the sentence, where the confusion between people was cleared up. The choice saying mis- means "too much" is wrong, because mis- never tells how much of something happens. The choice saying mis- means "without" is wrong, because mis- does not remove understanding, it changes it to the wrong kind. The choice saying mis- means "fully" is wrong, because mis- shows a mistake, not a complete or full action. Only "wrong" fits how mis- works in misunderstanding.

Question 15

1. trans-por-ta-tion (correct answer)
2. tran-spor-tat-ion
3. trans-port-a-ti-on
4. trans-por-tation

Explanation: Trans-por-ta-tion breaks the word into its correct four syllables. Tran-spor-tat-ion shifts the syllable breaks by a letter, which does not match the real sound pattern. Trans-port-a-ti-on splits the word into too many small pieces that do not match natural syllable sounds. Trans-por-tation combines the last two syllables into one, so it has too few syllable breaks.

Question 16

1. Read the whole word at once and guess its meaning from the sentence.
2. Break the word into un-re-li-a-ble, sound out each part, then blend them together. (correct answer)
3. Break the word into un-rel-iable and sound out each part.
4. Skip the prefix and read only re-li-a-ble.

Explanation: The correct answer breaks the word into its real syllables and blends them, which is the strategy skilled readers use for longer words. Choice A is wrong because guessing without sounding out the word can lead to misreading it. Choice C is wrong because it groups the letters into syllables that do not match how the word is actually broken up. Choice D is wrong because skipping the prefix leaves out part of the word's meaning and sound.

Question 17

1. Break it into in-ven-tion, sound out each syllable, and use -tion to signal a noun. (correct answer)
2. Break it into inven-tion, then sound out the first part quickly and skip over the middle syllable sound.
3. Break it into in-vent-ion, sound out each part, and treat -ion by itself as its own separate word.
4. Break it into in-ven-tion, sound out each syllable, and use -vent as the suffix that signals a noun.

Explanation: The best choice splits invention into in-ven-tion, sounds out each syllable, and knows that the suffix -tion signals the word is a noun. This uses both syllables and a real suffix correctly. One choice keeps inven as one chunk and then tells you to skip the middle syllable sound, but skipping a syllable means you lose part of how the word actually sounds. Another choice splits it as in-vent-ion and calls -ion its own separate word, but -ion is only part of the true suffix -tion, not a word on its own. The last choice breaks the syllables correctly but names -vent as the suffix; -vent is not a suffix, and it is the ending -tion that tells you the word is a noun. Only the first choice uses both the syllables and the suffix the right way.

Question 18

1. un-for-tu-nate-ly (correct answer)
2. un-fort-un-ate-ly
3. un-for-tun-ate-ly
4. un-for-tu-nat-ely

Explanation: The word unfortunately has five syllables: un-for-tu-nate-ly. Each part is a beat you can hear when you say the word slowly. The choice un-fort-un-ate-ly is wrong because it keeps the t with 'for' instead of starting the next syllable, so 'fort' takes a sound that belongs ahead. The choice un-for-tun-ate-ly is wrong because it pulls the n back to make 'tun,' splitting the middle sounds in the wrong place. The choice un-for-tu-nat-ely is wrong because it breaks between 'nat' and 'ely,' cutting the word after the wrong letter and leaving 'ely' instead of the clear ending 'nate-ly.' Only un-for-tu-nate-ly matches the beats you say when you sound the word out one syllable at a time.

Question 19

1. It means the word names a person who does the action.
2. It means the word names an action or process. (correct answer)
3. It means the word tells about something happening right now.
4. It means the word describes something, the way an adjective does.

Explanation: The suffix -tion turns a verb into a noun that names an action or process, so explanation means the act of explaining. The choice about naming a person is wrong because that job belongs to suffixes like -er or -or, not -tion. The choice about something happening right now is wrong because -tion does not show time or an ongoing action the way -ing can. The choice about describing something like an adjective is wrong because -tion builds a noun, not a describing word. Only naming an action or process fits the suffix -tion.

Question 20

1. together
2. before
3. wrongly or badly (correct answer)
4. again

Explanation: This question tests decoding unfamiliar multisyllabic words using letter-sound correspondences, syllabication, and morphology (CCSS.RF.4.3.a), specifically using word parts to determine meaning. To decode misunderstanding, students should identify the prefix mis- and the root understand, using knowledge of common prefixes. The prefix mis- means wrongly or badly, which combines with understand to mean understanding wrongly. Choice C is correct because it provides the correct meaning for the prefix mis-, demonstrating understanding of morphology. Choice A is incorrect because it assigns mis- the meaning of together, confusing it with prefixes like con- or com-; this error occurs when students confuse similar roots or don't know common prefixes. To help students decode unfamiliar multisyllabic words: Teach the THREE-STRATEGY APPROACH: (1) SYLLABICATION—Break word into syllables using patterns: VC/CV (rab-bit), V/CV (mu-sic), VC/V (cab-in), V/V (di-et), C-le (ta-ble). (2) PHONICS—Apply letter-sound knowledge to each syllable: read each syllable, then blend together; (3) MORPHOLOGY—Identify meaningful parts: prefixes (un-, re-, pre-, dis-, mis-), roots (port, dict, spect, tract), suffixes (-able, -tion, -ment, -ful, -less); practice with WORD FAMILIES and model think-aloud strategies.
