During a Latin class discussion, a student says: "I know that 'porto' means 'to carry,' so I think the English word 'export' must mean 'to carry something away from a place.'"

Is the student's reasoning about the English derivative correct, and what role does the prefix 'ex-' play in forming the meaning of 'export'?

The student is correct; 'ex-' means 'out of' or 'away from,' so 'export' means 'to carry out of' a place, which aligns with the modern English meaning of sending goods abroad.
The student is partially wrong; 'ex-' means 'into,' so 'export' actually means 'to carry into a place,' which is why it describes bringing goods into a new market.
The student is incorrect; 'porto' does not relate to carrying at all, and 'export' instead derives from the Latin word 'porta' meaning 'gate,' referring to goods passing through a gate.
The student is correct in the conclusion but wrong about the root; 'export' comes from 'portus' meaning 'harbor,' not 'porto,' so the connection to carrying is indirect and coincidental.

Question 1

During a Latin class discussion, a student says: "I know that 'porto' means 'to carry,' so I think the English word 'export' must mean 'to carry something away from a place.'"

Is the student's reasoning about the English derivative correct, and what role does the prefix 'ex-' play in forming the meaning of 'export'?

  1. The student is correct; 'ex-' means 'out of' or 'away from,' so 'export' means 'to carry out of' a place, which aligns with the modern English meaning of sending goods abroad. (correct answer)
  2. The student is partially wrong; 'ex-' means 'into,' so 'export' actually means 'to carry into a place,' which is why it describes bringing goods into a new market.
  3. The student is incorrect; 'porto' does not relate to carrying at all, and 'export' instead derives from the Latin word 'porta' meaning 'gate,' referring to goods passing through a gate.
  4. The student is correct in the conclusion but wrong about the root; 'export' comes from 'portus' meaning 'harbor,' not 'porto,' so the connection to carrying is indirect and coincidental.
Explanation: When you encounter questions about English derivatives from Latin roots, your job is to break the word into its parts — the prefix and the root — and analyze each one separately before combining them into a unified meaning. The Latin verb porto genuinely means "to carry," and this is one of the most productive roots in English. The prefix ex- (sometimes shortened to e-) is a Latin preposition and prefix meaning "out of" or "away from." You see it constantly: exit (to go out), expel (to drive out), extract (to pull out). So when you combine ex- + porto, you get "to carry out of" — which is precisely what exporting means in modern English: sending goods out of your country to another. The student's reasoning is sound, and answer A correctly captures this. Answer B fails because it inverts the meaning of ex-. "Into" is actually the meaning of the prefix in-, not ex-. Confusing these two opposites is a classic trap. Answer C is a creative distractor — porta does mean "gate" in Latin, and ports and gates are conceptually related to movement, but export does not derive from porta. The carrying root porto is well-documented and direct. Answer D introduces portus, meaning "harbor," which is etymologically related to the same Indo-European root as porto but is not the actual source of export. The connection isn't indirect or coincidental — porto is the direct root. Your study tip: memorize a short list of Latin prefixes like ex- (out), in- (into/not), sub- (under), and trans- (across). These unlock dozens of English derivatives on their own.

Question 2

During a class discussion about the Latin word 'magnus' (meaning 'great' or 'large'), a student says the English word 'magnify' means 'to make great or larger.' Another student challenges this, saying 'magnify' actually means 'to make seem larger' — not to literally enlarge something. Which of the following best evaluates this disagreement in terms of Latin vocabulary and English derivation?

  1. The second student is correct and the first is wrong; 'magnify' does not come from 'magnus' but from the unrelated Latin verb 'maneo' meaning 'to remain,' so it originally meant 'to stay large' and only later shifted to describe optical enlargement.
  2. The first student is correct and the second is wrong; 'magnify' derives from 'magnus' + '-fy' and always means literal physical enlargement — the notion of 'seeming larger' is a modern misuse not supported by the original Latin root meaning.
  3. Both students are essentially correct about the Latin root; 'magnify' comes from 'magnus' (great) combined with '-fy' (from 'facere,' to make), literally meaning 'to make great.' Whether it implies literal or apparent enlargement is a question of English usage, not Latin etymology. (correct answer)
  4. Both students are wrong; 'magnify' actually comes from 'magnes' (magnet) in Latin, referring to the way lenses were used with lodestones in ancient optics, so neither 'great' nor 'make' is relevant to the word's true origin.
Explanation: When a question asks you to evaluate a disagreement about Latin roots and English derivatives, your job is to separate two distinct questions: What does the Latin root mean? and How does English actually use the derived word? These are related but not identical. Here, both students are arguing about magnify, which breaks down cleanly into Latin components: magnus (great, large) + -fy, from the Latin verb facere (to make). Literally, then, "magnify" means "to make great." Both students actually agree on this underlying Latin foundation — they're just debating whether modern English usage implies literal or apparent enlargement. That debate belongs to English usage, not Latin etymology. Answer C correctly identifies this: both students are right about the root, and the disagreement is a usage question, not an etymological one. Answer A is a fabrication — "magnify" has no connection to maneo (to remain). This is a classic distractor that invents a false Latin source. Never let a confident-sounding false etymology fool you. Answer B overcorrects in the other direction by claiming the first student is entirely right. In reality, "magnify" routinely refers to apparent enlargement (as with a magnifying glass), so declaring this usage a "modern misuse" is inaccurate and overly rigid about what Latin roots require of English words. Answer D is entirely invented — magnes refers to lodestones/magnets and has no role in the etymology of "magnify." This is another false-root trap. Your study tip: always break a derivative into its Latin parts and confirm each component separately. Mixing up roots like magnus and magnes is a common trap — similar spellings don't mean shared origins.

Question 3

A student asks: "If 'bene' means 'well' in Latin and 'dico' means 'I say,' then does 'benediction' mean 'I say well'?" Which response most accurately corrects or confirms the student's analysis?

  1. The student is wrong; 'benediction' does not come from 'dico' at all, but from 'dictio' meaning 'a speech' combined with 'bene,' making it an entirely nominal compound with no connection to the verb 'I say.'
  2. The student is fully correct; 'benediction' is a direct transliteration of the first-person Latin phrase 'bene dico,' meaning 'I say well,' and it retains this verbal, first-person meaning in English religious contexts.
  3. The student is close but not fully accurate; 'benediction' does combine 'bene' (well) and a form of 'dico' (to say), but the noun suffix '-tion' makes it mean 'a saying of well' or 'a blessing,' not the first-person verb 'I say well.' (correct answer)
  4. The student is wrong about 'bene'; in compound words, 'bene-' shifts meaning to 'holy' or 'sacred' rather than 'well,' so 'benediction' means 'a holy proclamation' rather than anything related to the adverb 'well.'
Explanation: When analyzing Latin-derived English words, a smart approach is to break them into their component parts — prefix, root, and suffix — since each piece carries meaning. The suffix especially tells you what kind of word you're looking at: verb, noun, or adjective. The student correctly identifies both roots: bene (well) and a form of dico (to say). That's solid etymological thinking. However, the student stops too early. The English word benediction carries the suffix -tion, which is a Latin-derived nominal suffix that converts a verb into a noun meaning "the act of  ing." So benediction doesn't mean "I say well" — it means "a saying of well," or more naturally, "a blessing." Answer C captures this precisely: the student's root analysis is correct, but the grammatical conclusion is off because the suffix changes the word's part of speech entirely. Answer A is wrong because it claims benediction has "no connection" to the verb dico — but dictio itself is the noun form of dico, so the verbal root is absolutely present. A misleads you by drawing a false distinction. Answer B is wrong because benediction is not a first-person verb phrase frozen in time; the -tion suffix makes it a noun, and it does not retain a first-person verbal meaning in any context. Answer D invents a meaning shift for bene- that simply doesn't exist — bene consistently means "well" in Latin compounds, not "holy" or "sacred." Your study tip: always check the suffix last. Roots tell you the concept; suffixes tell you the grammatical role. Recognizing -tion as a noun-forming suffix will help you decode dozens of Latin-rooted English words.

Question 4

A Latin teacher asks the class: "The Latin word 'annus' means 'year.' Based on this, what does the English word 'perennial' most literally mean according to its Latin parts?"

A student answers: "'Perennial' means 'throughout the year' or 'lasting through many years,' because 'per-' means 'through' and 'annus' means 'year.'" Which evaluation of this answer is most accurate?

  1. The student is correct about the prefix but wrong about the root; '-ennial' in 'perennial' comes from 'ennea' (Greek for nine), not 'annus,' making 'perennial' relate to a nine-year cycle rather than a general sense of years.
  2. The student is correct; 'perennial' comes from Latin 'perennis' (per- + annus), meaning 'lasting through the year' or 'continuing for many years,' which is why it describes plants that survive multiple years or things that recur endlessly. (correct answer)
  3. The student is wrong about the prefix; 'per-' in 'perennial' does not mean 'through' but rather means 'very' or 'thoroughly,' so 'perennial' means 'very yearly' — describing something that happens with great regularity each year.
  4. The student is partially correct; while 'per-' does mean 'through,' the root is 'annis' (the dative form of 'annus'), so 'perennial' specifically means 'given to or belonging to years,' implying dedication over time rather than continuity.
Explanation: When you encounter questions about Latin roots and English vocabulary, the most reliable approach is to trace the word back to its actual Latin origin and analyze each component carefully. "Perennial" comes directly from the Latin adjective perennis, which is itself a compound of the prefix per- ("through, throughout") and annus ("year"). So the most literal meaning is "lasting through the year" or "continuing through many years" — exactly what the student said. This is why botanists use "perennial" to describe plants that survive and regrow across multiple growing seasons, and why we call a recurring problem a "perennial issue." The student's reasoning is sound, making B the correct evaluation. A is a creative-sounding distractor, but it's simply fabricated. The -ennial in "perennial" has nothing to do with the Greek ennea (nine). That confusion might arise from words like "ennead," but there is no nine-year cycle meaning hidden in "perennial." Watch out for answer choices that introduce plausible-sounding but invented etymologies. C misrepresents the prefix. While per- can intensify meaning in some Latin words (like perfectus), in perennis it carries its primary spatial/temporal meaning of "through." Claiming it means "very yearly" distorts both the Latin grammar and the word's actual usage. D invents a false grammatical detail. The root in perennis is not the dative form annis — the word is simply a compound noun-to-adjective formation. Dative case has no role here. Study tip: When analyzing English words for Latin roots, always look up the actual Latin source word rather than guessing from the English spelling alone — real etymology often surprises you.

Question 5

Two students are discussing the Latin word 'terra' (meaning 'land' or 'earth'). Student A says: "The word 'terrarium' must mean a container of land or earth." Student B says: "And 'Mediterranean' must also contain this root, since it means the sea in the middle of the land."

Which of the following correctly evaluates both students' claims about the Latin root 'terra'?

  1. Both students are correct; 'terrarium' uses '-arium' (a place/container for) plus 'terra,' and 'Mediterranean' combines 'medius' (middle) + 'terra' (land) + '-aneus' (adjective suffix), meaning 'in the middle of the land.' (correct answer)
  2. Student A is correct, but Student B is wrong; 'Mediterranean' derives from 'mare' (sea) and 'diterraneus' (distant), not from 'terra,' and simply means 'the far sea' in Latin.
  3. Student B is correct, but Student A is wrong; 'terrarium' actually comes from 'terror' (fear) and '-arium,' originally describing an enclosed space where fearsome animals were kept.
  4. Both students are partially wrong; 'terrarium' contains 'terra' correctly, but 'Mediterranean' uses 'terra' only in its secondary sense of 'territory,' not 'land,' making the two uses of 'terra' etymologically unrelated.
Explanation: When you encounter questions about Latin roots and word origins, your job is to trace each part of the word back to its Latin components and verify whether the meaning holds up. This question tests whether you can analyze compound words built from 'terra' (land/earth). Both students are actually right, and here's why. 'Terrarium' is a straightforward compound: 'terra' (earth/land) + '-arium,' a Latin suffix meaning "a place for" or "a container for" — the same suffix you see in 'aquarium' (a place for water) or 'vivarium' (a place for living things). Student A's analysis is clean and accurate. 'Mediterranean' breaks down just as neatly: 'medius' (middle) + 'terra' (land) + '-aneus' (an adjectival suffix), giving you "situated in the middle of the land" — which perfectly describes how ancient Romans viewed that sea, surrounded by landmasses. This makes A the correct answer. Choice B invents a false etymology, claiming 'Mediterranean' comes from 'diterraneus' meaning "distant." No such derivation exists — this is a fabricated distractor designed to test whether you'll second-guess a correct claim. Choice C flips the error onto 'terrarium,' falsely connecting it to 'terror.' While 'terror' and 'terra' look similar, they come from entirely different Latin roots ('terrēre' means "to frighten," not "earth"). Choice D introduces a fictional distinction between 'terra' as "land" versus "territory," claiming they're etymologically separate — they aren't. Both uses trace back to the same root word. A useful strategy: when analyzing compound words, break them into every component and verify each piece independently. Distractors often corrupt just one part of a word's etymology while leaving the rest plausible.

Question 6

In a vocabulary discussion, a student claims that because 'scribo' means 'to write' in Latin, the English word 'prescription' must mean 'something written.' Another student responds that the prefix 'pre-' changes the meaning importantly. Which answer most accurately captures what 'prescription' literally means based on its Latin parts?

  1. 'Prescription' means 'something written before' or 'a prior written order,' since 'pre-' means 'before' and 'scriptio' refers to a writing — together indicating instructions written in advance of treatment. (correct answer)
  2. 'Prescription' means 'something written for,' since 'pre-' is a shortened form of 'pro-' meaning 'for' or 'on behalf of,' indicating a document written on behalf of a patient.
  3. 'Prescription' means 'a secret writing,' since 'pre-' in this context derives from the Latin 'privus' meaning 'private,' indicating that only the pharmacist can interpret what is written.
  4. 'Prescription' means 'a writing about a problem,' since 'pre-' comes from 'prae-' meaning 'concerning' or 'regarding,' and the suffix '-tion' indicates the result of diagnosing before writing.
Explanation: When breaking down English vocabulary using Latin roots, your job is to analyze each part of the word separately and then combine their meanings logically. "Prescription" contains three parts: the prefix pre-, the root script- (from scribo, to write), and the noun suffix -ion (indicating an action or result). The prefix pre- comes directly from Latin prae-, meaning "before" — think of "preview" (see before) or "precaution" (caution taken before). Combined with scriptio (a writing), "prescription" literally means "a writing done beforehand" — instructions written in advance of treatment being administered. This is answer A, and it accurately reflects both the etymology and the real-world use: a doctor writes orders before the pharmacist dispenses medication. Answer B is tempting but wrong — pre- and pro- are distinct Latin prefixes with different meanings. Claiming pre- is a shortened pro- ("for") misrepresents how Latin prefixes work; they don't interchange this way. Answer C invents an etymology entirely. Pre- has no connection to privus ("private"). This distractor exploits the vague idea that prescriptions seem "coded," but that's not what the word means etymologically. Answer D is also fabricated. Prae- never meant "concerning" or "regarding" — that function belongs to prepositions like de- or pro-. The suffix -tion simply marks a noun, not a diagnostic process. Study tip: When analyzing Latin-derived English words, always treat prefixes with precision — pre- reliably means "before" across hundreds of English words, so memorizing it once pays dividends throughout the exam.

Question 7

A student is asked to explain how knowing the Latin word 'caput' (meaning 'head') helps understand the English word 'decapitate.' The student says: "'De-' means 'down' and 'caput' means 'head,' so 'decapitate' means 'to bring the head down.'" Which answer best assesses this explanation?

  1. The student is fully correct; in Latin, 'de-' exclusively means 'down,' and 'decapitate' literally means 'to force the head downward,' which is an accurate physical description of the act and perfectly matches the documented Latin usage of the prefix.
  2. The student is partially correct but imprecise; 'de-' can mean 'down' but here functions as a prefix meaning 'away from' or 'off,' so 'decapitate' more accurately means 'to remove the head away from the body,' not merely 'to bring the head down.' (correct answer)
  3. The student is wrong about both parts; 'de-' in this word comes from the Greek prefix meaning 'two,' and 'caput' refers specifically to the decorative top of a column in Roman architecture, so 'decapitate' originally described removing the upper section of a structure.
  4. The student is wrong about 'de-'; in all compound verbs without exception, 'de-' means 'completely' or 'thoroughly,' so 'decapitate' means 'to thoroughly deal with the head,' indicating a complete and final action rather than any sense of removal or separation.
Explanation: When studying Latin prefixes, it's rarely enough to know just one meaning of a prefix — most Latin prefixes carry a range of related meanings depending on context. The prefix de- is a perfect example: it can mean "down," "away," "off," or even signal reversal or removal. Knowing which sense applies requires looking at how the full word functions. The student's explanation in this question gets the root right (caput = head) but applies an overly narrow meaning to de-. The word decapitate means "to cut the head off the body" — a sense of separation or removal, not simply pressing something downward. Answer B correctly identifies this: de- here functions as "away from" or "off," making decapitate literally "to remove the head away from the body." That's the accurate, documented sense of the word. A is wrong because it doubles down on the student's error, claiming de- "exclusively" means "down." No Latin prefix works exclusively one way, and this narrow definition doesn't hold across the language. C fabricates information entirely — de- has no Greek origin meaning "two" (that would be di-), and caput refers to the head of a person or thing, not architectural ornamentation in this context. D is also wrong; while de- can sometimes intensify meaning (as in declare), it is absolutely not the rule for "all compound verbs without exception" — that's an overstatement designed to trap you. Your study tip: when you encounter de-, ask yourself whether the word implies removal (decapitate, detach) or downward motion (descend, depress). Context determines which meaning applies.

Question 8

A student is asked: "What English word meaning 'to make worse' comes from the Latin comparative adjective 'peior' meaning 'worse'?" The student answers 'deteriorate.' Is this answer correct, and what is the actual Latin-derived English word that most directly comes from 'peior'?

  1. The student is partially correct; 'deteriorate' does contain the root 'peior' in slightly altered form, but 'pejorative' is actually unrelated, deriving instead from the Latin noun 'pejus' meaning 'a lesser thing' rather than the comparative adjective.
  2. The student is correct; 'deteriorate' does come from 'peior,' since a 'd-' prefix was added in Medieval Latin to intensify the root, and 'pejorative' is simply an alternative spelling of the same derived word used in different contexts.
  3. The student is wrong; neither 'deteriorate' nor 'pejorative' comes from 'peior' — both derive from the Latin verb 'detero' meaning 'to wear away,' and 'peior' left no surviving derivatives in the English language.
  4. The student is wrong; 'deteriorate' comes from 'deterior,' a distinct Latin comparative also meaning 'worse,' and the English word most directly from 'peior' is 'pejorative,' meaning tending to express disapproval or make something seem more negative. (correct answer)
Explanation: When you encounter questions about Latin roots and English derivatives, your best strategy is to trace each word back to its specific Latin origin rather than assuming similar-looking words share the same source. In this case, the key distinction is between two different Latin comparatives. Deterior is its own Latin adjective meaning "worse" or "lower," and it gave us deteriorate — meaning to grow worse over time. Separately, peior (also spelled pejor) is the comparative of malus meaning "bad," and it most directly produced pejorative, an adjective describing language that expresses contempt or makes something seem worse. These are two distinct Latin words that happen to share similar meaning, not one word with a prefix added. Answer D correctly captures this: the student misattributed "deteriorate" to peior when it actually descends from deterior, and the true heir of peior in English is "pejorative." Answer A is wrong because it correctly identifies the problem with the student's answer but then invents a fictional Latin noun pejus as the source of "pejorative" — pejorative does come from peior, not some separate noun. Answer B is wrong on multiple levels: deteriorate does not come from peior with a prefix, and "pejorative" is absolutely not an alternative spelling of "deteriorate" — they are entirely different words with different meanings. Answer C is wrong because it falsely claims peior left no English descendants and misidentifies detero ("to wear away") as the shared origin of both words. A useful tip: on Latin-derived vocabulary questions, watch for false cognates — words that look related but have distinct origins. Always verify the specific Latin root, not just the general meaning.

Question 9

A student reads the Latin sentence: "Puella aquam portat." The teacher then asks the class: "Which English word meaning 'related to water transport systems' is a derivative of the Latin word for water found in this sentence?"

Which answer correctly identifies the Latin word for water in the sentence and its most direct English derivative related to water transport?

  1. 'Aquam' is the Latin word for water, and 'aquatic' is the most direct derivative related to water transport, since the Latin suffix '-ticus' was used specifically to designate infrastructure and systems associated with a given resource or element.
  2. 'Aquam' is the Latin word for water, and 'aquifer' is the most direct derivative related to water transport, combining 'aqua' with 'ferre' (to carry) to mean 'a carrier of water,' which accurately describes the function of both underground water layers and ancient channels.
  3. 'Portat' contains the Latin root for water transport, since 'porto' originally referred specifically to carrying water in Roman domestic contexts, making 'portable' the most direct derivative — it described vessels designed to carry water from place to place.
  4. 'Aquam' is the Latin word for water (accusative form of 'aqua'), and 'aqueduct' is the most direct derivative related to water transport, combining 'aqua' with 'ductus' (a leading or channel) to mean 'a channel that leads water' — precisely describing Roman-engineered water systems. (correct answer)
Explanation: When you encounter a question asking you to trace an English word back to its Latin roots, your best approach is to break the derivative into its component parts and verify that each part matches a genuine Latin source. In the sentence "Puella aquam portat," the word aquam is the accusative form of aqua, meaning "water" — it's in the accusative case because it functions as the direct object of portat ("carries"). The most direct English derivative related to water transport is aqueduct, making D correct. The word combines aqua (water) with ductus, derived from ducere (to lead or channel). An aqueduct is literally "a channel that leads water," which perfectly describes the elaborate Roman engineering systems that transported water across long distances into cities. A is tempting because aquatic does come from aqua, but the claim that the Latin suffix -ticus specifically designated infrastructure or systems is fabricated. Aquatic simply means "relating to water," not specifically to water transport systems. B is partially correct — aquifer does combine aqua with ferre (to carry) — but the reasoning overreaches. An aquifer is a geological formation that holds groundwater; it is not an engineered transport system and was not an ancient Roman construction term. Aquifer is also a much more modern coinage than aqueduct. C is entirely wrong. Portat comes from portare (to carry in a general sense), which has nothing to do with water specifically. The claim that porto originally referred to carrying water is invented. When studying Latin derivatives, always decompose the word into its roots and verify each part independently — don't be misled by answers that get one element right but fabricate the rest.

Question 10

A classmate argues that the English word 'audio' is a direct borrowing from the Latin verb 'audio' meaning 'I hear,' and that therefore 'auditorium' must mean 'a place where hearing happens.' Which response best evaluates this claim?

  1. The claim is essentially correct; English 'audio' derives from the Latin verb 'audire' (to hear), whose stem gives the first-person form 'audio,' and the suffix '-torium' in Latin denotes a place associated with an action, so 'auditorium' literally means 'a place for hearing.' (correct answer)
  2. The claim is partially wrong; while 'auditorium' does relate to hearing, the English word 'audio' actually derives from the Latin noun 'auditus' meaning 'the sense of hearing,' not from the verb form, so the first-person connection the classmate describes is incorrect.
  3. The claim is correct about 'auditorium' but wrong about 'audio'; the English word 'audio' comes from the Greek word 'audios' meaning 'sound,' while only 'auditorium' traces back to the Latin verb 'audire,' making the two words etymologically unrelated.
  4. The claim is entirely incorrect; both 'audio' and 'auditorium' derive from the Latin noun 'auris' meaning 'ear,' not from any Latin verb, and the connection to 'I hear' is a common student misconception about how Latin nouns and verbs relate.
Explanation: When you encounter questions about Latin word origins, the key is tracing the root, stem, and suffix systematically rather than assuming a word comes from one specific Latin form. The Latin verb audire means "to hear," and its stem aud- runs through an entire family of related English words. The first-person singular present tense of audire is indeed audio, meaning "I hear." English borrowed audio directly from this Latin verb system, using the root to mean anything related to sound or hearing. The suffix -torium is a genuine Latin construction meaning "a place for" or "a place associated with" a particular action — think dormitorium (a place for sleeping) or laboratorium (a place for working). So auditorium literally and accurately means "a place for hearing." Answer A captures this completely and correctly. Answer B is wrong because it claims audio derives from the Latin noun auditus rather than the verb audire. While auditus does exist and means "the sense of hearing," the English word audio traces to the verbal root, not this noun form. The distinction B draws is fabricated to sound technical. Answer C invents a Greek word audios that simply does not exist. Latin and Greek have separate word families for sound and hearing — audio has no Greek origin. Answer D confuses aud- with auris (ear). While auris is a real Latin noun for "ear," it belongs to a different root and gives us words like aural, not audio or auditorium. Your study tip: memorize Latin suffixes like -torium (place), -or (agent/doer), and -io (action/process) — they unlock dozens of English vocabulary questions.
