📖 Rule & Word Origin

In English, idiomatic expressions must be used correctly to convey the intended meaning. The phrase "pour down the drain" typically means to waste something rather than a literal action.

💡 Usage & Examples

- **Correct:** She poured the leftover soup down the drain. - **Incorrect:** She poured them down the rain. (This is incorrect as it combines idioms incorrectly.)

🔍 Option Analysis

- **(a) She collected:** No error here; the subject and verb are correctly matched. - **(b) some armful of medicines and:** "Some armfuls" would be correct to indicate the plural. - **(d) No error:** Incorrect, as there is an error in option (c).

⚡ Grammatical Traps & Mnemonics

Remember: "Pour down the drain" means to waste. Think of "armful" needing to be in plural when referring to more than one.
