200 mL, 2 mL are very small estimates for the amount of water fillied in the water jug.

2,000 L is too big for the estimate for the amount of water filled in the water jug.

Approximately 2 L of water can be filled in the water jug shown.

So, the best estimate for the amount of water filled in the water jug is 2 L.

1 liter is too small to measure the capacity of a water can.

50 liters, 10 liters are too big to measure the capacity of a water can.

So, the best estimate of the capacity of a water can is 2 liters.

The weight of the camera can be lighter than 1 kilogram.

So, the best estimate for the weight of the camera is lighter than 1 kilogram.

The bottle can hold about 1 liter.

So, the estimate for the capacity of the bottle shown is about 1 liter.

The objects in Figure 2 and Figure 3 cannot hold 1 litre.

The object in Figure 1 can hold less than 1 litre.

So, among the given objects, the object in Figure 1 can hold about 1 litre.

A cup and a tablespoon cannot hold 50 litres of water. They are too small to hold 50 litres of water.

A water jug can hold a maximum of 5 litres of water.

Usually people store plenty of water in tanks. So, a tank can hold 50 litres of water.

100 kilograms and 10 kilograms are too big to measure the weight of a papaya.

10 grams is too small to measure the weight of a papaya.

A papaya can weigh about 2 kilograms.

So, the estimated weight of a papaya is 2 kilograms.

Weight of the potato shown cannot be 1 g, or 5 g, or 7 g. It can be around 75 g.

So, the best estimate for the weight of the potato shown is 75 g.

The given object is a syringe.

Weight of a syringe cannot be 1 kg or 5 kg or 100 kg, it can be around 25 g.

So, the correct estimate for the weight of the given object is 25 g.

The given object is a pen.

Weight of the pen cannot be 2 kg, or 5 kg, or 50 kg. It can be around 50 g.

So, the best estimate for the weight of the pen shown is 50 g.
