Answer
a. 4 m b. 100 g c. 5 litres
Explanation
## Step1 For the height of a traffic light pole, 4 cm and 40 cm are too short. Traffic light poles are similarly sized to lamp posts, typically taller than humans. Conversely, 40 m would be excessively tall for a traffic light pole. ## Step2 When it comes to the mass of an orange, 10 g is too light, and 1 kg and 10 kg are too heavy for a typical orange. Thus, 100 g is the most common weight for an orange.## Step3 In reference to the amount of water in a filled kettle, 50 ml and 500 ml may be too little, and 50 litres is definitely too much. A standard kettle usually contains around 1 to 2 litres of water when filled to maximum capacity. Therefore, the choice closest to this range is 5 litres.
