Describing Past Background DetailsQuestion 1 of 10

During a speaking assessment, a student is asked: '¿Cómo te sentías el primer día de tu trabajo nuevo?' The student responds: 'El primer día, me sentí muy nervioso porque no sabía nada y todos los demás empleados parecían muy seguros de sí mismos.'

The student uses a mix of preterite and imperfect in the response. Which analysis correctly identifies whether each verb choice is appropriate for describing past background details?

Me sentí is correct as a completed emotional experience on that day; no sabía should be no supe because the lack of knowledge was a definitive condition established at a specific moment, making it a completed state; and parecían is correct for the ongoing impression of coworkers.
Me sentí (preterite) is an error and must be replaced with me sentía because any feeling described in response to a first-day experience is by definition a background emotional state; no sabía is correct as an ongoing condition; and parecían is correct as an ongoing impression of others.
Me sentí (preterite) is defensible because nervousness on one specific day can be framed as a completed emotional experience; no sabía (imperfect) is appropriate for an ongoing state of not knowing; and parecían (imperfect) is appropriate for the sustained impression of coworkers. All three choices are grammatically acceptable.
All three verbs should be preterite (me sentí, no supe, parecieron) because the question anchors all details to el primer día — a single completed day — and a specific past date requires preterite for every verb in the response, including states and impressions.

Question 1

During a speaking assessment, a student is asked: '¿Cómo te sentías el primer día de tu trabajo nuevo?' The student responds: 'El primer día, me sentí muy nervioso porque no sabía nada y todos los demás empleados parecían muy seguros de sí mismos.'

The student uses a mix of preterite and imperfect in the response. Which analysis correctly identifies whether each verb choice is appropriate for describing past background details?

  1. Me sentí is correct as a completed emotional experience on that day; no sabía should be no supe because the lack of knowledge was a definitive condition established at a specific moment, making it a completed state; and parecían is correct for the ongoing impression of coworkers.
  2. Me sentí (preterite) is an error and must be replaced with me sentía because any feeling described in response to a first-day experience is by definition a background emotional state; no sabía is correct as an ongoing condition; and parecían is correct as an ongoing impression of others.
  3. Me sentí (preterite) is defensible because nervousness on one specific day can be framed as a completed emotional experience; no sabía (imperfect) is appropriate for an ongoing state of not knowing; and parecían (imperfect) is appropriate for the sustained impression of coworkers. All three choices are grammatically acceptable. (correct answer)
  4. All three verbs should be preterite (me sentí, no supe, parecieron) because the question anchors all details to el primer día — a single completed day — and a specific past date requires preterite for every verb in the response, including states and impressions.
Explanation: When analyzing past tense verb choices in Spanish, the key question is always: does this verb describe a completed action/state, or an ongoing background condition? Preterite captures events that happened and ended; imperfect captures states, habits, or conditions that were ongoing at the time. In this student's response, me sentí (preterite) describes nervousness as a bounded, completed emotional experience tied to that specific first day — a feeling that occurred and resolved. This is entirely defensible. No sabía (imperfect) captures an ongoing state of not knowing that existed throughout that day, not a single moment of realization. Parecían (imperfect) reflects a sustained impression of coworkers — something the student observed continuously, not a one-time event. All three choices are grammatically sound, making C correct. Answer A incorrectly claims no sabía should be no supe. Saber in preterite (supe) typically signals a moment of finding out or learning something new — not a pre-existing state of ignorance. The student's lack of knowledge was a background condition, so imperfect is right. Answer B wrongly insists me sentí must become me sentía. Emotions can appear in either tense depending on framing — preterite treats the feeling as a completed episode, which is perfectly valid for a reaction tied to one defined day. Answer D falls into a classic trap: assuming that a specific time marker like el primer día forces every verb into preterite. Time markers anchor the story, but they don't override the ongoing/completed distinction for each individual verb. Study tip: Always ask about each verb individually — does it describe a snapshot or a backdrop? Time markers set the scene but never automatically determine tense.

Question 2

A student is completing a speaking task and says the following to describe a childhood memory: 'De niño, mi familia vivía en el campo. La casa era pequeña pero acogedora. Mi perro se llamaba Roco y era muy juguetón. Yo tenía ocho años y me gustaba mucho explorar el bosque cerca de nuestra casa.'

A classmate claims that se llamaba should be replaced with se llamó because a dog's name is a fixed, definitive fact — not an ongoing condition — and fixed facts in the past take the preterite. Which response best refutes or supports this claim?

  1. The classmate is correct because names are unique identifying facts attached to a specific moment — the act of naming — and any reference to a name in a past description should use the preterite to acknowledge that the naming was a completed, bounded event.
  2. The classmate is incorrect. Se llamaba is appropriate because the dog's name was a continuous identifying characteristic during the childhood period being described. The imperfect is standard for names and titles used as background descriptive detail; it describes what something was called, not the act of naming. (correct answer)
  3. The classmate is partially correct: se llamó would be required only if the dog later changed its name or died during the period being described, since those events would create a definitive endpoint; without such a change, se llamaba is acceptable as a default.
  4. The classmate is incorrect, but the reason is that llamarse is a reflexive verb, and reflexive verbs in Spanish always default to the imperfect when they describe personal or identifying characteristics, regardless of whether the characteristic was ongoing or completed at a specific point.
Explanation: When describing past scenes, memories, or background conditions in Spanish, you need to distinguish between the preterite (completed, bounded actions) and the imperfect (ongoing states, descriptions, and habitual conditions). This passage is a classic childhood memory narrative — everything in it functions as descriptive background, which is exactly where the imperfect thrives. B is correct because se llamaba describes the dog's name as a continuous identifying characteristic throughout the childhood period being recalled. Names and titles used as background description follow the imperfect because you're painting a picture of what something was called, not narrating the act of naming. Every other verb in the passage — vivía, era, tenía, gustaba — is imperfect for the same reason: they all describe the ongoing state of things, not discrete events. A is wrong because it confuses two different things: the act of naming (which would indeed be a completed event, lo llamaron Roco) versus describing what something was called over time. The classmate's logic sounds reasonable but misidentifies what se llamaba is actually expressing. C is wrong because it invents a grammatical rule that doesn't exist. Whether or not the dog later changed its name is irrelevant to tense selection here. The imperfect doesn't require an open-ended future — it just requires an ongoing state within the described period. D is wrong because reflexive verbs have no blanket rule requiring the imperfect. Reflexive verbs follow the same preterite/imperfect logic as all other verbs. Study tip: When you see names, ages, physical descriptions, or emotional states in a past narrative, default to imperfect — these are descriptive background, not plot events.

Question 3

For a conversational assessment, students must describe a past memory using at least four background details. Valentina says: 'Cuando tenía quince años, vivía en una ciudad grande. Mi escuela quedaba lejos de mi casa, así que todos los días tomaba el autobús. El autobús siempre estaba lleno y el viaje duraba cuarenta minutos. Me aburría mucho durante el trayecto.'

Valentina's description includes six imperfect-tense verbs. A reviewer claims that duraba should be changed to duró because the forty-minute duration is a measurable, specific quantity that implies a completed, bounded event. Which response most accurately evaluates this claim?

  1. The reviewer is correct because any time expression involving a specific number (forty minutes, three hours, two years) signals a bounded duration and therefore requires the preterite to mark the completion of that measured period, regardless of whether the event was repeated.
  2. The reviewer is incorrect because duraba is required whenever the subject of a sentence is an inanimate object or event (such as a bus ride), since inanimate subjects cannot perform completed actions and therefore always take the imperfect when describing past situations.
  3. The reviewer is correct, but only partially: duró is required here because durar is an achievement verb that inherently encodes the endpoint of an event, so its past-tense form must always be preterite regardless of whether the context is habitual or not.
  4. The reviewer is incorrect. Duraba is appropriate because Valentina is describing the habitual, repeated duration of the bus ride as a background detail of her daily routine. The imperfect expresses habitual past conditions, and a commute that lasted forty minutes every day is precisely that kind of recurring background detail. (correct answer)
Explanation: When analyzing past-tense verb choices in Spanish, always ask yourself two questions: Is the action completed and viewed as a whole, or is it a repeated/ongoing background condition? and Does the surrounding context establish a habitual routine? These questions cut straight to the preterite vs. imperfect distinction. Here, Valentina explicitly frames everything as daily routine — "todos los días tomaba el autobús," "siempre estaba lleno." Within that habitually recurring context, duraba describes how long the ride used to last each day, not a single completed trip. The forty-minute figure is simply the characteristic duration of a repeated background event, which is exactly what the imperfect expresses. D is correct: duraba fits perfectly as a habitual, background detail embedded in a description of past routine. A is wrong because specific numbers do not automatically trigger the preterite. A number like "forty minutes" can describe how long something habitually took. The decisive factor is habituality and context, not numerical precision. B is wrong because the animacy of a subject is grammatically irrelevant to tense selection. Inanimate subjects can absolutely appear with preterite verbs ("El tren llegó tarde"), so this rule is entirely fabricated. C is wrong because durar is not an achievement verb with an inherent endpoint that forces the preterite. It is a durative verb that describes ongoing stretches of time, and it comfortably takes the imperfect when describing habitual situations. Study tip: When you see a specific quantity in a habitual context (every day, always, usually), default to the imperfect — the number describes the recurring condition, not a one-time completed event.

Question 4

Elena está hablando con su amigo sobre cómo era su vida cuando tenía diez años. Ella dice: 'Cuando era niña, vivía en un apartamento pequeño cerca del mar. Todos los veranos, mi familia y yo íbamos a la playa. El agua estaba fría, pero nosotros nadábamos de todas formas. Me sentía muy feliz en esos momentos.'

Elena describes several background details about her childhood. Which of the following best identifies the grammatical structure she uses to describe her emotional state during those summers, and why is that structure appropriate here?

  1. She uses the preterite sentí because the feeling occurred at a specific, completed moment during a single summer visit, making it a bounded past event. The preterite signals that the emotion began and ended on one particular occasion.
  2. She uses the imperfect me sentía because the feeling was a recurring, habitual emotional state across those summers — exactly the function of the imperfect when describing background feelings in the past. (correct answer)
  3. She uses the imperfect me sentía because the imperfect is always required after the time expression en esos momentos, regardless of whether the action is habitual or completed.
  4. She uses the preterite sentí because verbs like sentirse always appear in the preterite when the emotion is directed at a past experience, since the experience itself is now over and fully completed.
Explanation: When reading Spanish passages about the past, your first instinct should be to ask: is this a one-time, completed event, or an ongoing condition/repeated habit? That distinction drives the choice between preterite and imperfect — and it's exactly what this question tests. In the passage, Elena uses me sentía to describe her emotional state during those summers — plural, repeated, backdrop feelings. The imperfect is precisely the right tool here because it paints emotional states as ongoing background conditions rather than single, bounded events. Feelings like happiness that colored an entire era of childhood summers are classic imperfect territory. B captures this perfectly: me sentía signals a recurring emotional state that served as the backdrop to those experiences, which is the core function of the imperfect tense. A is wrong because it misidentifies the verb form — the passage uses me sentía, not sentí — and then builds a false justification around it. The preterite would only be appropriate if Elena were pointing to one specific, isolated moment when the feeling began or ended, which the context does not support. C is tempting but contains a dangerous overgeneralization: the imperfect is not automatically required after en esos momentos. Tense choice depends on meaning and context, never on a fixed time expression trigger. Don't fall for rules that sound tidy but ignore meaning. D is wrong twice over: the verb form is again misidentified as preterite, and the reasoning — that a finished experience forces preterite on the feeling — is a fabricated rule with no grammatical basis. A reliable tip: when you see emotions, mental states, or descriptions in a past-tense passage, they almost always call for the imperfect unless a specific, sudden shift in feeling is highlighted.

Question 5

During a Spanish class role-play, Marcos is asked to describe what his hometown was like when he was a teenager. He says: 'Mi ciudad   muy tranquila. No   mucho tráfico y la gente siempre   amable con los turistas.'

Marcos needs to fill in all three blanks with the correct imperfect forms of the verbs ser, haber, and ser (in that order) to accurately describe the background setting of his hometown. Which option correctly completes all three blanks?

  1. era / había / era — imperfect of ser for the city's overall character, imperfect of haber as an existential verb describing a background condition, and imperfect of ser again for a recurring characteristic trait of the people (correct answer)
  2. fue / hubo / fue — preterite of ser, preterite of haber, and preterite of ser throughout, because the description refers to a finished period of his life that is now over and therefore treated as a set of completed past events
  3. era / hubo / era — imperfect of ser for the city's character and for the people's behavior, but preterite of haber to indicate that the lack of traffic was a notable, one-time circumstance rather than a habitual background condition
  4. fue / había / era — preterite of ser for the first blank because the city's character changed at a definite point, imperfect of haber for the traffic condition, and imperfect of ser for the people's typical behavior
Explanation: When describing background conditions, settings, or habitual states in the past, Spanish uses the imperfect tense — not the preterite. The key question to ask yourself is: Was this a completed, one-time event, or an ongoing condition/repeated characteristic? Marcos is painting a picture of what his hometown was generally like — classic imperfect territory. All three blanks describe background conditions: the city's overall character (tranquila), the typical absence of traffic, and the people's habitual friendliness. None of these are single, completed events — they're all ongoing states or repeated patterns. This makes A (era / había / era) correct. The imperfect of ser captures enduring characteristics, and the imperfect of haber (había) describes an existential background condition (how much traffic there generally was), not a specific occurrence. Choice B (fue / hubo / fue) uses the preterite throughout, which would imply each item was a distinct, finished event with a clear endpoint — like "the city was peaceful on one particular day." Describing a teenager's entire experience of a hometown this way is grammatically inappropriate. Choice C (era / hubo / era) correctly uses the imperfect for ser but mistakenly uses the preterite hubo for traffic, treating a habitual background condition as if it were a one-time notable occurrence — that's the trap. Choice D (fue / había / era) mixes tenses illogically, applying the preterite to ser in the first blank without any justification that the city's character changed at a specific moment. Your study tip: when you see descriptive language about how things "used to be" — especially characteristics, weather, emotions, or typical routines — default to the imperfect. The preterite interrupts; the imperfect sets the scene.

Question 6

Sofía is telling her conversation partner about the day she moved to a new school. She says: 'Recuerdo que el primer día, yo   catorce años y   muy nerviosa. El edificio   enorme y no   a nadie todavía.'

Sofía wants to describe her age, emotional state, the building's appearance, and the fact that she did not yet know anyone — all as background details for that day. Which set of verb forms correctly fills all four blanks (in order)?

  1. tenía / estaba / era / conocía — imperfect for age, imperfect of estar for an ongoing temporary emotional state, imperfect of ser for an inherent physical characteristic of the building, and imperfect for a continuous background state of not knowing anyone (correct answer)
  2. tuve / estuve / fue / conocí — preterite for age, preterite of estar for the emotional state, preterite of ser for the building's size, and preterite for acquaintances — all bounded completed events because the entire memory is tied to one specific day
  3. tenía / estuve / era / conocía — imperfect for age, preterite of estar to mark the nervousness as a sudden onset of feeling on that specific morning, imperfect of ser for the building's size, and imperfect for the ongoing lack of acquaintances
  4. tenía / estaba / fue / conocía — imperfect for age, imperfect of estar for the emotional state, preterite of ser for the building because its large size is a factual characteristic that existed as a completed, verifiable reality on that specific day, and imperfect for acquaintances
Explanation: When describing background conditions in a past narrative — age, emotions, physical descriptions, ongoing states — Spanish uses the imperfect tense. Think of the imperfect as painting the scene: it sets the stage rather than advancing the plot. The preterite, by contrast, marks completed, bounded actions that move the story forward. In Sofía's sentence, every blank describes a background detail on that day: how old she was, how she felt, what the building looked like, and the ongoing reality that she didn't know anyone yet. None of these are sudden events or completed actions — they are all static conditions that were simply true in the background. That makes answer A correct: tenía / estaba / era / conocía — all four verbs in the imperfect. Age (tener) is always expressed in the imperfect for past descriptions. Estar in the imperfect captures an ongoing emotional state, not a sudden emotional shift. Ser in the imperfect describes an inherent physical characteristic of the building. And conocía reflects a continuous background state of not yet knowing anyone. Answer B uses all preterites, which would imply each detail was a discrete completed event — but feeling nervous or being fourteen aren't events that "happened and ended." Answer C mixes in estuve (preterite of estar), which would suggest her nervousness suddenly began at a specific moment, which Sofía isn't saying. Answer D uses fue (preterite of ser) for the building's size — but physical characteristics of places are classic imperfect territory, not completed facts. Your study tip: when you see age, feelings, physical descriptions, or mental states in a past context, default to the imperfect unless something signals a sudden change or completed action.

Question 7

A student is practicing interpersonal communication and wants to say: 'When I was little, I was afraid of the dark and I couldn't sleep without a light on.' She produces the sentence: Cuando era pequeña, tenía miedo de la oscuridad y no podía dormir sin una luz encendida. Her partner challenges her, arguing that tuve miedo and pude should be used instead because fear and ability 'happened' to her in the past. Which response best evaluates the student's original sentence?

  1. The partner is correct because tener miedo and poder describe internal events that happen to a person, and internal events always require the preterite to mark the moment of their occurrence and emotional impact on the subject.
  2. The student is correct because both tenía miedo and no podía describe continuous background states — an ongoing fear and a persistent inability — which are core imperfect functions when describing habitual past context introduced by cuando era pequeña. (correct answer)
  3. The student is partially correct: tenía miedo is right because fear is a mental state, but no podía should be no pude because inability in the past always represents a specific, concrete result and therefore requires the preterite to signal that outcome.
  4. The partner is partially correct: tuve miedo is appropriate because the childhood fear represents a phase of life that is now completely over, but no podía is correct because habitual inability is expressed with the imperfect regardless of how long ago it occurred.
Explanation: When choosing between the preterite and imperfect in Spanish, ask yourself: does this past action/state have a clear beginning and end (preterite), or does it describe an ongoing condition, habit, or background state (imperfect)? The phrase cuando era pequeña is your biggest clue here — it sets up a habitual, repeated childhood backdrop, which signals that the imperfect is the natural tense to use for everything inside that frame. The student's sentence is fully correct, making B the right answer. Both tenía miedo de la oscuridad and no podía dormir describe continuous background states: the fear wasn't a single moment of fright, and the inability to sleep wasn't one specific failed attempt — they were persistent, recurring conditions throughout her childhood. This is exactly what the imperfect is designed to express. Answer A is wrong because it invents a rule that doesn't exist. Internal events do not "always" require the preterite. The preterite of tener miedo (tuve miedo) signals a sudden, punctual onset of fear — like being startled — not a long-standing childhood condition. Answer C incorrectly claims that inability always represents a concrete result demanding the preterite. No pude would mean she tried and failed on one specific occasion; no podía correctly captures a habitual, ongoing inability. Answer D misapplies the logic of "a phase being over." The preterite isn't triggered simply because something happened long ago or has ended — it requires a clearly bounded, completed event, which a vague childhood phase does not provide. Your key strategy: let the context verb tell you the tense. Cuando era pequeña frames everything as background habit — let the imperfect follow naturally throughout.

Question 8

Read the following short conversation between two Spanish students practicing past descriptions:

Ana: ¿Cómo era tu casa de la infancia? Beto: Era grande y (1)tuvo muchas ventanas. (2)Había un jardín enorme donde mis hermanos y yo (3)jugábamos todos los días. Me (4)encantaba ese lugar.

Beto's description contains one error in verb tense. Which numbered verb is incorrect, and what is the best explanation for why it should be changed?

  1. Verb (2) había is incorrect and should be hubo because the garden is a specific feature of a specific house, making it a definite, completed fact rather than a general background condition.
  2. Verb (3) jugábamos is incorrect and should be jugamos because playing in the garden happened on identifiable days in the past, which requires the preterite to anchor the action to real, finished occasions.
  3. Verb (1) tuvo is incorrect and should be tenía because the many windows were a permanent physical characteristic of the house — a background descriptive detail that requires the imperfect, not the preterite. (correct answer)
  4. Verb (4) encantaba is incorrect and should be encantó because feelings of love or strong preference (encantar) are always expressed in the preterite when referring to a past place or object that no longer exists in one's life.
Explanation: When describing the past in Spanish, the key question to ask is: Is this verb expressing a background condition, or a completed action/event? The imperfect tense handles ongoing states, habitual actions, and descriptive details — the "backdrop" of a story. The preterite handles specific, completed events that moved the narrative forward. In Beto's description, everything is painted as a nostalgic, ongoing backdrop: how the house used to be, what existed there, what the brothers would do regularly, how he felt. This context signals that the imperfect should dominate — and it does, except in one place. Verb (1), tuvo, uses the preterite of tener, but it's describing a permanent physical characteristic of the house — the windows. This is exactly the kind of static, descriptive detail that requires the imperfect tenía. Nothing "happened" with those windows; they were simply part of the house's enduring description. Answer A is a trap because había (imperfect of haber) is perfectly correct — the garden's existence is a background feature being described, not a one-time event. Answer B is wrong because jugábamos correctly uses the imperfect for a habitual, repeated activity ("we used to play every day"). The phrase todos los días is actually a strong signal for the imperfect. Answer D is wrong because encantaba is also correct — emotions and feelings in descriptive past contexts use the imperfect, and there is no rule requiring encantar to take the preterite. Study tip: When you see tener in a past description, ask yourself: Is something being described, or did something happen? If it's a characteristic or state, always reach for tenía.

Question 9

A student wants to express the following idea in Spanish using correct past-tense background description: 'My grandmother was seventy years old, she had white hair, and she always wore a blue apron when she cooked.' She writes: Mi abuela tenía setenta años, tenía el pelo blanco, y siempre llevaba un delantal azul cuando cocinaba. Which analysis of this sentence is most accurate?

  1. The sentence is correct. All four imperfect forms (tenía, tenía, llevaba, cocinaba) are appropriate: they describe age, physical appearance, habitual clothing, and the habitual activity that formed the background context — all classic imperfect functions in past description. (correct answer)
  2. The sentence has one error: the second tenía (for white hair) should be tuvo because physical traits that are permanent and unchanging are described with the preterite in Spanish to signal they are established, completed facts rather than ongoing conditions.
  3. The sentence has two errors: llevaba should be llevó and cocinaba should be cocinó because both actions occurred specifically during cooking sessions, tying them to a bounded, repeated activity that requires the preterite to mark each instance as completed.
  4. The sentence has one error: siempre llevaba should be siempre llevó because the adverb siempre in past contexts signals a definitive, summarized pattern of behavior — a completed habit viewed as a whole — which requires the preterite rather than the imperfect.
Explanation: When describing past scenes in Spanish, you need to ask yourself: what kind of past action is this? The imperfect tense handles ongoing states, physical descriptions, ages, and habitual or repeated actions — essentially the "background wallpaper" of a past story. The preterite, by contrast, marks specific completed events with a clear beginning and end. In this sentence, every verb fits the imperfect perfectly. Tenía setenta años expresses age — a classic imperfect use. The second tenía describes physical appearance (white hair), another ongoing state. Siempre llevaba describes a habitual, repeated action in the past (she always wore it, over and over), and cocinaba provides the background activity that framed her wearing the apron — also habitual and ongoing. All four verbs are doing exactly what the imperfect is designed to do, making A the correct answer. B is wrong because it invents a rule that doesn't exist. Spanish does not use the preterite for permanent or unchanging physical traits. Whether a trait was temporary or lifelong, if you're describing it as an ongoing background condition, the imperfect is correct. C is wrong because it misidentifies habitual repetition as a reason for the preterite. In fact, the opposite is true — habitual past actions (she always wore, she always cooked) are a core function of the imperfect, not the preterite. D is wrong because siempre does not trigger the preterite. The adverb siempre reinforces habituality, which pairs naturally with the imperfect, not against it. Study tip: When you see siempre, nunca, todos los días, or similar frequency words in a past-tense context, they almost always signal the imperfect — they emphasize ongoing habit, not a single completed event.

Question 10

Two students are arguing about how to translate this sentence into Spanish: 'It was raining and the streets were flooded when we arrived at the hotel.' Student 1 says: 'Llovía y las calles estaban inundadas cuando llegamos al hotel.' Student 2 says: 'Llovió y las calles estuvieron inundadas cuando llegamos al hotel.' Which student is correct, and which grammatical principle best explains the answer?

  1. Student 2 is correct because cuando followed by a completed action (llegamos) requires all surrounding verbs to shift to the preterite in order to maintain tense agreement within the clause, treating the rain and flooding as co-occurring completed events.
  2. Student 2 is correct because the flooding and rain are observable, factual conditions directly tied to the specific moment of arrival; conditions linked to a precise moment are expressed with the preterite to signal that they coincided with and were bounded by that event.
  3. Student 1 is correct, but only because weather verbs like llover must always be conjugated in the imperfect in past-tense Spanish, while state verbs like estar can appear in either tense; therefore llovía is forced imperfect and estaban inundadas is a separate choice by the speaker.
  4. Student 1 is correct because llovía and estaban inundadas are background conditions — ongoing atmospheric and physical states already in progress when the completed arrival (llegamos) occurred. Background conditions use the imperfect; the event that occurs against that background uses the preterite. (correct answer)
Explanation: When translating a past-tense narrative in Spanish, your first move should be to classify each verb: is it describing a background condition (ongoing, already in progress) or a completed event (a specific action that happened)? That classification determines whether you use the imperfect or the preterite. In this sentence, the rain and the flooded streets were already happening when the group arrived. They form the scene — the backdrop against which the arrival occurred. That's the job of the imperfect: painting the background. The arrival (llegamos) is a single, completed action that punctuates that background — that's the preterite. Student 1's version (llovía... estaban inundadas... llegamos) captures this perfectly, making D the correct answer. A is wrong because Spanish does not require tense agreement the way some students assume. The word cuando doesn't force surrounding verbs into the preterite — in fact, cuando + preterite (llegamos) is precisely the signal that a completed event interrupted ongoing background conditions. B is wrong because it confuses "observable" or "factual" with "completed." The flooding was certainly real and observable, but it was an ongoing state, not a bounded event with a clear start and end — that's imperfect territory, not preterite. C is wrong because weather verbs like llover are not locked into the imperfect. Llovió (preterite) is perfectly grammatical when describing a single, completed episode of rain. The tense choice depends on context, not verb category. Study tip: When you see a past-tense sentence with cuando, ask yourself: what was already in progress, and what happened? Background → imperfect; event → preterite.
