The inference that can be drawn from the observation that there are four birds on the bird feeder is that the birds must be hungry. This is because birds typically visit a bird feeder when they are in need of food. Therefore, the presence of four birds suggests that they are hungry and seeking food from the feeder.Rate this question:

The desks are rectangular.
- B.
The desks are 1.5 meters long.
Correct Answer
B. The desks are 1.5 meters long.Explanation
The quantitative observation in this question is "The desks are 1.5 meters long." This is because it provides a specific measurement (1.5 meters) which can be quantified and compared. The statement "The desks are rectangular" does not provide a specific measurement and is therefore not a quantitative observation.Rate this question:
