+2. `git reflog`
+   ![alt text](3.png)
+
+3. Explanation
+    - `git reset`:  Adjusts the position of HEAD (the current branch pointer) to a specified commit, with different effects depending on the mode selected:
+        - **soft**: Moves HEAD to the target commit without affecting the staging area (index) or working directory (tree).
+        - **mixed** (default): Moves HEAD and updates the staging area to match the target commit, without changing the working directory.
+        - **hard**: Moves HEAD, updates the staging area, and modifies the working directory to match the target commit.
+    - `git reflog`: Logs all movements of HEAD (commits, resets, checkouts, and rebases) on the current branch, allowing you to track recent changes to branch history. 
+    - `HEAD~<int>` A reference to a commit relative to HEAD
+    - `HEAD~3` Refers to three commits before HEAD
