Identify the part of the sentence that contains a grammatical error: 'By the time the police arrived (A), the thieves already escaped (B) with the jewels (C), leaving no trace behind (D).'
💡 Explanation
When two actions happen in the past, the action that occurred first should be in the Past Perfect tense (had + V3). The thieves escaped before the police arrived, so it should be 'had already escaped'.

Which part of the sentence contains an error? 'The construction company has been working (A) on this bridge project (B) for last January (C) without any breaks (D).'
💡 Explanation
The preposition 'since' is used to indicate a starting point in time (e.g., since January, since 2020), while 'for' is used to indicate a duration of time (e.g., for three months). It should be 'since last January'.

My brother lived (A) in London for five years (B) and he still enjoys (C) his life there (D). Identify the error.

Choose the grammatically correct sentence.
💡 Explanation

Identify the error: After the main course had been served (A), the waiters brought (B) the dessert and then (C) had collected the plates (D).
💡 Explanation
The actions of bringing the dessert and collecting the plates happened sequentially after the first action. They should both be in the Past Indefinite tense. The sentence should be '...the waiters brought the dessert and then collected the plates.' Using Past Perfect ('had collected') is incorrect here.
Identify the part of the sentence with a grammatical error: 'The farmer had plowed (A) the field after the sun (B) had risen (C) and warmed the earth (D).'
💡 Explanation
The rule is that the action which occurs first takes the Past Perfect tense ('had' + V3). Since the sun rose first, 'had risen' is correct. The plowing happened after, so it should be in the Past Indefinite tense ('plowed'), not 'had plowed'.
She ______ on her thesis without a break ______ the beginning of the semester.
💡 Explanation
The action started in the past and is still ongoing, requiring the Present Perfect Continuous ('has been working'). 'The beginning of the semester' is a specific point in time, which requires the use of 'since'.

💡 Explanation
The preposition 'for' is used to denote a duration or period of time (e.g., five years). 'Since' is used to denote a specific starting point in time (e.g., since 2018). 'Since more than' is incorrect; it should be 'for more than'.

He ______ that he ______ a terrible mistake as soon as he ______ the email.
💡 Explanation
The mistake happened first, so it requires the Past Perfect ('had made'). The realization and the sending of the email happened afterward (and simultaneously), so they both take the Past Indefinite tense ('realized', 'sent').

💡 Explanation
The preposition 'since' is used for a specific point in time (like the year 1947). The preposition 'for' is used for a duration of time (like 'for 75 years'). The use of 'for' with a specific year is incorrect.
