Explanation

"I asked who had done it."

The original sentence is a direct question in past tense ("Who did it?").

In reported speech:

The reporting verb "said" changes to "asked" (as it's a question)

The past simple "did" changes to past perfect "had done" (standard tense change in reported speech)

The question structure changes to indirect statement structure (no question mark needed)

The word order changes from question form to statement form

Explanation

"You told me that water freezes at 0°C."

The original sentence is a statement of a general/scientific fact ("Water freezes at 0°C").

In reported speech:

• "Said to" changes to "told" (more natural for reported speech)
• The tense remains present ("freezes") because it's a universal truth
• The conjunction "that" is properly used
• The factual information remains unchanged

Explanation

"They exclaimed with disgust that there was a cockroach there."

The original sentence shows an exclamation ("Ooch!") expressing disgust at seeing a cockroach.

In reported speech:

• The interjection "Ooch!" becomes "exclaimed with disgust"
• The present tense "is" changes to past tense "was"
• "Here" changes to "there" (as required in reported speech)
• The conjunction "that" is added

This makes "who" a relative pronoun.

It replaces the unknown information (in this case, the name).
