Step-by-step explanation:

I'm taking the test and see that they say 500 kg was the mass of the horses today. So the youngest is the closest to 500 kg right? And it also said the oldest was the less mass so that is why it is...

Answer 2

Based on the information given we'll list the horses from most mass to least mass since we want to start at the youngest fossil and so:

270kg, 150kg, 80kg, 50kg = B C A D

Note that youngest fossil means it's the most recent since and old fossil would be really old in age.
