🧠 Explanation of Reasoning

Let’s go through each comparison based on typical real-world weights:

1. Glue stick vs. Scissors
- A standard glue stick weighs about 10–20 grams.
- A pair of plastic-handled scissors weighs around 50–100 grams.
→ Scissors are heavier.

2. Stapler vs. Ruler
- A small desktop stapler weighs ~100–150 grams.
- A wooden ruler (30 cm) weighs about 20–30 grams.
→ Stapler is heavier.

3. Notebook vs. Pencil
- A small spiral notebook weighs ~100–200 grams.
- A standard pencil weighs ~5–10 grams.
→ Notebook is heavier.
