Answer
### a. 6 m, b. 100 g, c. 2 litres
Explanation
## Step 1: Determine the height of a lamp post### 6 cm and 60 cm are too short for a lamp post, while 60 m is excessively tall. Therefore, 6 m is the most reasonable estimate.## Step 2: Determine the mass of a pear### 10 g is too light, and 1 kg and 10 kg are too heavy for a typical pear. Thus, 100 g is the most reasonable estimate.## Step 3: Determine the amount of water in a filled kettle### 20 ml is too little, and 20 litres is too much for a kettle. A kettle typically holds around 1 to 2 litres of water. Therefore, 2 litres is the most reasonable estimate.
