ANSWER KEY & EXPLANATIONS
1 (B) will answer
Explanation: A spontaneous decision made right when the doorbell rings requires “will”. Option (A) is a common mistake, as “am going to” is used for pre-planned intentions. Option (C) is a structural error (will + V-ing). Option (D) is a meaning trap; present simple is not used for instant decisions.
2 (D) will see
Explanation: “Will” followed by the base verb is used to offer immediate help or action. Option (A) is a structural error (will + to V). Option (B) is a common mistake (present continuous is for fixed arrangements). Option (C) is grammatically incorrect here.
3 (A) will
Explanation: The decision to check the door is made at the moment of speaking. Option (B) is a common mistake since there was no prior plan. Option (C) is a structural error (adding “s” to will). Option (D) is a severe structural error.
4 (C) will
Explanation: Reacting instantly to the doorbell ringing again. Option (B) is a common mistake and also misses the “am”. Option (A) is a structural error. Option (D) is a meaning trap; you are deciding now, not already in the middle of doing it.

GRAMMAR POINTS TO REMEMBER
- Instant Decisions: Use “Will + Base Verb” when you make a decision at the exact moment of speaking. It is a spontaneous reaction to a situation (e.g., The doorbell rings → “I will open it”).
- The “Be going to” Trap: Do not use “be going to” for sudden situations or instant offers. “Be going to” is strictly used when you already have a plan or intention before the moment of speaking.
- The Golden Structure Rule: The modal verb “will” must always be followed by a bare infinitive (base verb). Never use “will to V”, “will V-ing”, “will V-ed”, or “will V-s”.
- The Present Simple Trap: In many languages, people use the present simple tense for immediate actions (e.g., “I open the door”). In English, this is incorrect; you must use the future form “will” to show your commitment to doing the action right away.
