Fill in the blank correct verb : Scarcely had the CEO concluded her speech when the shareholder ______ to their feet.

Explanation:

This sentence follows a standard grammar pattern:

👉 Scarcely/Hardly + had + subject + V3 (past participle) + when + subject + V2 (simple past)

• First clause: had concluded → Past Perfect
• Second clause: needs Simple Past → rose

❌ Why other options are incorrect?

• had risen ❌ → Past Perfect (not needed again)
• had rose ❌ → Wrong form (had + V3 should be risen, not rose)
• were risen ❌ → Incorrect and unnatural structure

📘 Verb Forms of “rise”:

• V1: rise

💡 Key Rule to Remember:

After Scarcely/Hardly, use:

• Past Perfect in the first clause
• Simple Past in the second clause
