Examen Diagnóstico de Inglés V | A2+ & B1

This describes an established general practice ('nowadays' as a broad period), so the present simple with plural agreement is correct.

This describes a gradual, developing trend over time, which in English is expressed with the present continuous ('is becoming'), not the static present simple.

'Every four hours as standard procedure' describes a routine, which requires the present simple; plural subject 'Nurses' takes the base form, not '-s'.

The action is happening at this exact moment ('right now'), so the present continuous is required, not the habitual present simple or a completed present perfect action.

'Every year' signals a repeated, general fact, which takes the present simple with third-person -s, not a temporary continuous action.

Two sequential completed past actions connected by 'and then' both take the past simple.

The background action in progress at a specific past moment ('at 9 a.m. yesterday, while...') takes the past continuous.

'This is the first time I have...' is a fixed structure using the present perfect to describe an experience happening for the first time.

After 'has never', the verb must be in the past participle form to complete the present perfect structure.

'Last year' is a specific, finished time reference, so the past simple is required instead of the present perfect.

'Have never been to' is the fixed present perfect form used for life experience; 'been' is the correct past participle of 'be' after 'have'.

The subject (the medicine) receives the action of making, and the process is a general, ongoing fact, so present simple passive is required.

'What steps' asks generally about the sequence of actions, the natural choice when the options aren't a limited, known set.

The question asks about the manner or method of a process, which is introduced by 'How', not by a question word about reason, time, or place.

'How long' is the fixed phrase used to ask about duration.

'Which department' is used because it implies choosing among a known, limited set of departments in the institution.

The question is about the mechanism or method of protection, which requires 'How'.

'Might' expresses an uncertain possibility, matching 'isn't sure'; 'must' would suggest near-certainty, which contradicts the uncertainty in the sentence.

'Even though' introduces a concession: despite lacking training, she still succeeded — a contrast, not a cause.

'Even though' signals a contrast between a drawback (side effects) and the outcome (it's still recommended).

'Because' gives the reason (the investment) behind the result (reduced emissions).

'Should' matches a professional recommendation; 'must' would overstate it as an obligation rather than advice.

'So' connects the situation (not passing) with the resulting plan (retaking it).

'Could you please...?' is a standard polite, formal request structure; the other options are either informal contractions or grammatically inappropriate.

'Really' is the adverb that correctly modifies the adjective 'hard' in casual spoken English; 'real' is a common error since it's an adjective, not an adverb.

'Suggest' is followed by a gerund (-ing form), not an infinitive, when recommending an activity.

'I would appreciate it if you could...' is a standard polite, formal request pattern used in professional emails.

'Writing to apply' uses the infinitive of purpose, the standard structure in formal application letters.

'But' introduces the contrast between acknowledging the other person's point and still disagreeing.

'To sum up' is the fixed phrase used to introduce a conclusion or summary of a discussion.

After the modal 'can', the base form of the verb is required, and 'say something' (not 'tell something') is the correct collocation.

After 'would you like to', the base form of the verb is required.

After the subject 'I', the base form of the present simple verb is required, not a past tense, gerund, or the incorrect 'am agree'.

'Last year' places the passive action in a finished past time, requiring the past simple passive.

'Because' introduces the reason (lack of data) for the rejection.

'Suggest' is followed by the gerund form of the verb, not the infinitive or base form.

After 'has never', the past participle is required to complete the present perfect structure.

'Might' expresses a tentative future possibility depending on a condition ('if the data looks promising'), which fits better than the obligation of 'must' or 'should'.

The passage states panels work best in sunny climates, mentions government subsidies as encouragement, and calls sunlight renewable. It says storage batteries remain costly (not cheap) and that prices have dropped, not increased.

The passage confirms internships help exploration, build networks, and that unpaid ones may offer academic credit. It says some internships are unpaid (not all paid), and counselors recommend at least two internships, not just one.
