Understanding Direct and Indirect Speech Conversion

The question asks us to convert a sentence from indirect speech to its correct direct speech form. The original sentence is: "They said that they had already completed their homework."

Rules for Converting Indirect to Direct Speech

To convert indirect speech to direct speech, we need to follow specific grammar rules:

• Remove the conjunction 'that'.
• Introduce the reported speech with a comma after the reporting verb (e.g., 'said').
• Enclose the reported speech within quotation marks (" ").
• Change the pronouns and possessive adjectives to reflect the speaker's perspective. The third-person pronouns ('they', 'their') used in indirect speech often change to first-person ('we', 'our') when converting to direct speech, assuming the original speakers are reporting their own words.
• Adjust the verb tense. Typically, tenses shift back in indirect speech. When converting back to direct speech, the tense reverts to its original form. A Past Perfect tense ('had completed') in indirect speech usually corresponds to a Present Perfect ('have completed') or Past Simple ('completed') in the original direct speech.
• Keep time and place adverbs as they were, or adjust if necessary depending on the context (though not applicable here).

Step-by-Step Conversion Analysis

Let's break down the original indirect sentence and apply the conversion rules:

• Reporting Verb: "They said" remains the same.
• Conjunction: Remove "that".
• Pronoun Change: The indirect speech uses "they" and "their". Since the reporting verb is "They said", the direct speech likely involves the speakers referring to themselves. Therefore, "they" changes to "We" and "their" changes to "our".
• Verb Tense Change: The indirect speech has the Past Perfect tense "had already completed". This tense typically originates from the Present Perfect tense in direct speech. So, "had already completed" reverts to "have already completed". The adverb "already" remains.
• Punctuation: Add a comma after "said" and enclose the direct speech in quotes.

Putting it together: They said, "We have already completed our homework."

Evaluating the Options

Now let's check the given options against our derived direct speech sentence:

• Option 1: They said, "We already completed their homework." - Incorrect. It uses the wrong possessive adjective ("their" instead of "our") and the Past Simple tense ("completed") might not be the most accurate conversion from Past Perfect, plus the structure is slightly off.
• Option 2: They said, "We have completed our homework." - Incorrect. It correctly uses "We" and "our", and the Present Perfect tense, but it misses the adverb "already".
• Option 3: They said, "We have already completed homework of ours." - Incorrect. While it uses the correct tense and includes "already", the phrasing "homework of ours" is grammatically awkward and less common than "our homework".
• Option 4: They said, "We have already completed our homework." - Correct. This option perfectly matches our step-by-step conversion, correctly changing the pronouns ("they" to "We", "their" to "our"), adjusting the verb tense ("had completed" to "have completed"), keeping the adverb "already", and using proper punctuation.

Final Conclusion

The correct direct speech form accurately reflects the original statement with the necessary changes in pronouns, tense, and punctuation, as demonstrated in Option 4.
