Question 1
The board appointed Lena Ortiz treasurer. In that role, Ortiz submitted the annual accounts to board and met with auditor hired to review them.
Which sequence of articles correctly completes the passage?
- a; the; an
- the; a; the
- no article; the; an (correct answer)
- no article; a; the
Explanation: When filling in articles, you need to ask three questions for each blank: Is this the first mention or a repeated/unique reference? Does the noun start with a vowel sound? And does context make the noun specific?
The first blank follows "appointed Lena Ortiz treasurer." When someone is appointed to a role or title, English treats that title as a bare predicate noun — no article at all. We say "She was elected president" or "He served as captain," not "a president" or "the captain." So the first blank takes no article, confirming answer C is on the right track.
The second blank refers to "the board." The board has already been introduced in the very first sentence, so it's a known, specific entity to both speaker and reader — that's exactly when you use the. This rules out answer D, which places "a" here, incorrectly treating the board as if it were unspecified.
The third blank requires "an auditor." This is the first and only mention of the auditor, so no prior context makes them definite. Because "auditor" begins with a vowel sound, the indefinite article must be an, not "a." This eliminates answer A (which gets the first blank wrong with "a") and answer B (which uses "the" for the auditor despite it being a first mention, and "a" for the board despite it being already established).
Your takeaway: always scan backwards through the passage before choosing an article. If a noun has appeared before or represents a unique/shared reference, use the. If it's a title after "appointed/elected/named," use no article at all.
Question 2
The documentary follows climbers from Netherlands as they train near Mount Kilimanjaro before beginning a research voyage across Indian Ocean.
Which sequence of articles correctly completes the passage?
- no article; the; the
- the; no article; the (correct answer)
- the; the; no article
- no article; no article; the
Explanation: When dealing with articles before proper nouns and place names, the key question is whether the noun belongs to a category that conventionally takes "the." English uses "the" with country names that include a common noun (the United Kingdom, the United States), with mountain ranges, oceans, rivers, and seas — but not with individual mountain names or standalone country names.
Working through the blanks: "the Netherlands" requires the definite article because the name historically references a plural/descriptive term ("the low lands"), placing it in the category of countries that always take "the." Next, "Mount Kilimanjaro" is an individual, named peak — singular mountains with the word "Mount" in their title never take an article. Finally, "the Indian Ocean" requires "the" because all oceans, seas, and large bodies of water take the definite article as a rule. This makes B (the; no article; the) correct.
Choice A fails immediately because omitting the article before "Netherlands" is grammatically wrong — it's one of a small group of countries that always require "the." Choice C makes the opposite error with Kilimanjaro, incorrectly inserting "the" before a proper mountain name with "Mount." Choice D compounds the error from A (dropping "the" before Netherlands) while also dropping the necessary article before "Indian Ocean," leaving two blanks incorrect.
A reliable strategy: memorize the three article-always categories — oceans/seas, countries named with a plural or descriptive word, and mountain ranges (the Alps, the Rockies). Individual mountains with "Mount" are the counterexample to watch for, as they never take "the."
Question 3
honeybees communicate information about food through movement, but honeybees in this observation hive behaved unusually when researchers recorded them with camera mounted above the colony.
Which sequence of articles correctly completes the passage?
- the; the; the
- no article; no article; a
- no article; the; a (correct answer)
- the; no article; the
Explanation: When working with English articles (a, an, the, or no article), ask yourself two questions for each noun: Is it definite (specific/known) or indefinite (general/unknown)? Is it countable or uncountable?
The sentence has three blanks. The first blank precedes "honeybees" in a general statement — we're talking about honeybees as a species, not a specific group. General plural nouns take no article in English ("Dogs are loyal," not "The dogs are loyal"). The second blank also precedes "honeybees," but now the sentence specifies which honeybees: those "in this observation hive." That restrictive phrase makes them a definite, specific group, so the is required. The third blank precedes "camera," a singular countable noun introduced for the first time with no prior context — the classic case for the indefinite article a. This makes C (no article; the; a) correct.
Choice A is wrong because using the before the first "honeybees" implies a previously established specific group, which contradicts the general, universal claim being made. Choice B fails because the second "honeybees" is clearly defined by the phrase "in this observation hive," so omitting the article produces an ungrammatical and logically vague sentence. Choice D misplaces the on the camera — since the camera hasn't been mentioned before, readers have no referent, making a the only appropriate choice there.
A useful rule of thumb: the first mention of a singular countable noun almost always takes a/an; use the only when the noun is identifiable through context, prior mention, or a modifying phrase that restricts its meaning.
Question 4
trust is difficult to build, but trust that residents placed in the mayor disappeared after financial scandal.
Which sequence of articles correctly completes the passage?
- the; the; the
- no article; a; the
- a; no article; a
- no article; the; a (correct answer)
Explanation: When working with articles in English, you need to ask three questions for each blank: Is this noun specific or general? Is it being mentioned for the first time or referred back to? Is it countable or uncountable?
Take each blank in turn. The first blank pairs with "trust" in a general, abstract sense — the idea that trust is hard to build universally. Because "trust" is an uncountable noun used in a sweeping generalization, no article is needed. The second blank refers to "the trust that residents placed in the mayor" — a specific, identifiable trust defined by the relative clause that follows. This specificity demands the definite article "the." The third blank introduces "financial scandal" for the first time, and since it's a singular countable noun appearing without prior context, it takes the indefinite article "a." That gives you no article / the / a — answer D.
Choice A incorrectly uses "the" in the first blank, which would imply a previously identified or uniquely specific trust rather than a general concept. Choice B uses "a" in the second blank, but "a" signals something non-specific or introduced for the first time — the relative clause ("that residents placed in the mayor") makes this trust definitively specific, so "the" is required. Choice C uses "a" before "trust" in the first blank, which is impossible because "trust" here is uncountable and abstract; indefinite articles don't work with uncountable nouns used generically.
A reliable tip: whenever a noun is followed by a defining relative clause (like "that residents placed in the mayor"), it becomes specific — and specific nouns almost always call for "the."
Question 5
experience in negotiation is valuable, but chairing the emergency meeting was unsettling experience for Priya. Nevertheless, experience strengthened her confidence.
Which sequence of articles correctly completes the passage?
- an; an; an
- the; a; the
- no article; the; an
- no article; an; the (correct answer)
Explanation: When choosing articles, you need to ask three questions for each blank: Is the noun countable or uncountable? Is it being introduced for the first time or already known? Is it specific or general?
The first blank pairs with "experience" used as an uncountable, general noun — it refers to the abstract quality of having experience, not a specific event. Uncountable nouns used generically take no article, so "no article" is correct here. The second blank also uses "experience," but now it's countable and indefinite — one particular unsettling event being introduced for the first time. Because "unsettling" begins with a vowel sound, it requires an, not "a." The third blank refers back to that same specific experience already mentioned — the chairing of the emergency meeting. Since both writer and reader now know exactly which experience is meant, it becomes definite, requiring the. This gives you the sequence: no article / an / the — answer D.
Choice A fails because "an experience" in the first blank incorrectly treats a general, uncountable use of "experience" as a countable singular event. Choice B uses "the" in the first blank, which would imply a previously established specific experience that doesn't exist in context, and "a" in the second blank ignores that "unsettling" starts with a vowel sound (requiring "an"). Choice C correctly identifies the first blank but then uses "the" for the second — wrong because the unsettling experience is being introduced, not previously known.
Your study tip: memorize the three-step article check — countable or not → new or known → general or specific. This sequence catches the most common article errors on grammar exams.
Question 6
As a pupil, Noah goes to school each weekday. Yesterday, however, his mother went to school to repair a window and spoke with principal about the damage.
Which sequence of articles correctly completes the passage?
- the; the; a
- no article; no article; the
- the; no article; the
- no article; the; the (correct answer)
Explanation: When choosing articles in English, the key distinction is between generic/institutional use and specific/physical reference. Certain nouns like school, church, hospital, and prison drop the article entirely when referring to their primary, abstract purpose — but take the when referring to the physical building or location itself.
In the first blank, Noah attends school as a student fulfilling its core institutional function. No article is needed here — just as you'd say "she's in hospital" (British) or "he went to prison." In the second blank, his mother visits the school — she's going to a specific building to fix a window, not participating in school as an institution. The article the is required because it's a definite, physical reference. In the third blank, she speaks with the principal — a specific, identifiable person at that school — so the is again correct. This makes D (no article; the; the) the right sequence.
Choice A fails because placing the before the first "school" implies Noah is heading to a specific building rather than attending school institutionally. Choice B removes both articles from the school references, but the second visit is clearly to a definite, physical location that requires the. Choice C commits the opposite error from A — it correctly uses the for the mother's visit but wrongly strips the article before "principal," who is a specific individual requiring the.
A useful rule of thumb: if you can mentally replace the noun with "the institution of ," drop the article. If you're pointing to a specific place or person, the is your signal.
Question 7
During the same week, the clinic treated one patient with flu, another with severe cold, and a third for diabetes.
Which sequence of articles correctly completes the passage?
- no article; the; a
- a; the; no article
- the; a; no article (correct answer)
- the; no article; a
Explanation: When completing a sentence with articles, you need to ask three questions for each blank: Is this noun countable or uncountable? Is it being introduced for the first time or already known? Does it name a specific or general thing?
"The flu" is the correct phrase for the first blank because flu (short for influenza) is treated as a definite, familiar concept in English — we say "the flu" the same way we say "the sun" or "the internet," referring to a well-understood, singular phenomenon. This makes C correct: the flu, a severe cold, no article before diabetes.
For the second blank, "a severe cold" works because cold is a countable noun being introduced for the first time with no prior reference — exactly when the indefinite article a applies. The modifier "severe" doesn't change this logic; a simply precedes the adjective.
For the third blank, diabetes is an uncountable (mass) noun referring to a medical condition in general. Uncountable nouns used in a general sense take no article, just like cancer, depression, or hypertension.
Now for the wrong answers: A incorrectly drops the article before flu, treating it like an uncountable general noun, which ignores English's idiomatic convention of always saying "the flu." B uses a before flu, which would imply flu is just one type among countable options — unnatural in standard usage. D places the correctly before flu but then drops the article before cold, which is countable and needs a on first mention.
Your study tip: memorize a short list of illnesses that break the pattern — "the flu," "the measles," "the mumps" always take the, while most other diseases (diabetes, cancer, asthma) take no article.
Question 8
During her first visit to the archive, Leila requested manuscript on maritime law without naming a specific title. When the clerk brought one, she discovered that manuscript was only surviving copy from the period.
Which sequence of articles correctly completes the passage?
- a; the; the (correct answer)
- the; a; the
- a; the; an
- the; the; an
Explanation: When choosing articles, always ask yourself two questions: Is this the first time this noun is mentioned, or has it been introduced before? and Is this noun unique or specifically identified? The answers tell you whether to use a/an (indefinite — introducing something new or non-specific) or the (definite — referring to something already known or uniquely identifiable).
Working through the passage: In the first blank, Leila requests a manuscript she hasn't specified — it's one of many possible manuscripts, introduced for the first time. That calls for the indefinite article a. In the second blank, "the manuscript" refers back to the specific one the clerk already brought — it's now a known, previously mentioned item, so the is correct. In the third blank, the manuscript is described as the "only surviving copy," meaning it's unique and singular in the world. Uniqueness signals the. This gives you the sequence a / the / the, which is answer A.
Answer B fails immediately because using "the" in the first blank implies the manuscript was already known to both Leila and the clerk — but the passage explicitly says she gave no specific title. Answer C gets the first two blanks right but stumbles on the third: "an only surviving copy" treats uniqueness as just another trait rather than a definitive identifier, and grammatically, "only" here doesn't begin with a vowel sound requiring "an." Answer D repeats the error of B in the first blank and compounds it with the same "an" mistake in the third.
Your strategy: track nouns across a passage like a thread — first mention gets a/an, subsequent mentions or uniquely defined items get the.
Question 9
Because the patient needed MRI scan, the technician copied the files to USB drive after hour-long delay.
Which sequence of articles correctly completes the passage?
- an; a; an (correct answer)
- a; an; a
- an; an; a
- a; a; an
Explanation: When choosing between "a" and "an," the rule isn't about the letter a word starts with — it's about the sound. Use "an" before words that begin with a vowel sound, and "a" before words that begin with a consonant sound. This distinction trips up many students because spelling can be misleading.
Apply this to each blank: "MRI" is pronounced "em-ar-eye," so it begins with the vowel sound "em" — requiring "an." "USB" is pronounced "you-es-bee," beginning with the vowel sound "you" — also requiring "an." Finally, "hour-long" begins with a silent "h," so the word opens with the vowel sound "ow" — again requiring "an." This makes the correct sequence an, an, an... except "USB" starts with a vowel sound ("you"), so yes, all three need "an," confirming choice A.
Choice B ("a; an; a") incorrectly uses "a" before "MRI," ignoring that "em" is a vowel sound, and incorrectly uses "a" before "hour," ignoring the silent "h." Choice C ("an; an; a") gets the first two right but fails on "hour-long" — the silent "h" means you're really hearing a vowel sound at the start, so "an" is required, not "a." Choice D ("a; a; an") makes errors on both "MRI" and "USB" while correctly identifying "hour-long."
A reliable study tip: when you see abbreviations or acronyms, say them aloud. The sound of the first letter — not how it's written — always determines whether you use "a" or "an."
Question 10
We usually commute by train, but today we missed 7:15 train and had to take taxi to the office.
Which sequence of articles correctly completes the passage?
- the; a; the
- no article; the; a (correct answer)
- no article; a; the
- a; the; no article
Explanation: When choosing articles in English, ask yourself three questions: Is this noun countable or uncountable? Is it being mentioned for the first or second time? Is it specific and mutually understood between speaker and listener?
"Train" in the first blank refers to a general mode of transportation — it's habitual, not a specific train. Uncountable or generic uses of nouns like this take no article ("we travel by train," "we go by car"). The second blank introduces a specific train — the 7:15 — which is a particular, identifiable departure, so it takes the, signaling shared knowledge between speaker and listener. The third blank refers to a taxi taken as one instance among many possible taxis, introduced here for the first time, so it takes the indefinite article a. This makes B (no article; the; a) correct.
Choice A fails immediately because "the train" in the first blank implies a specific train, contradicting the general habitual meaning of commuting "by train." Choice C gets the second blank wrong — "a 7:15 train" would imply the listener doesn't know which train is meant, but a specific departure time makes the train definitively identifiable, requiring the. Choice D stumbles on all three: "a train" wrongly treats commuting as a countable instance, "the taxi" implies a previously mentioned or mutually known taxi (there's no such context), and dropping the article before "7:15 train" is grammatically incorrect for a countable noun.
A useful tip: transportation modes used habitually (by bus, by plane, by train) never take an article. Save the for nouns whose identity is already established by context or detail.
