Error spotting (exam direction): Identify the erroneous part (A/B/C) in the sentence — choose D if there is no error — 'Everyone visiting the house asked the young girl / how could she kill the wolf / single handed and without a weapon. / No error.'

Given sentence parts (A–D)
A. Everyone visiting the house asked the young girlB. how could she kill the wolfC. single handed and without a weapon.D. No error.

Concept/Approach (reported/indirect speech word order)
After verbs like 'asked', 'wanted to know', etc., the embedded (reported) question should use statement word order (subject + verb), not the inverted question order (auxiliary + subject).

Step-by-Step correction
1) Identify the reported question: 'how could she kill the wolf'.2) Change to statement order: 'how she could kill the wolf' (also acceptable: 'how she could have killed the wolf' depending on narrative tense).3) Improved sentence: 'Everyone visiting the house asked the young girl how she could kill the wolf, single-handed and without a weapon.'

Verification/Alternative
Compare: Direct Q → 'How could she kill…?' vs. Indirect → '…asked how she could…'

Common pitfalls
Keeping the interrogative inversion ('could she') inside indirect speech; omitting the hyphen in 'single-handed'.

Final Answer
B — 'how could she kill the wolf' is incorrect; use 'how she could kill the wolf'.
