Question

a summary is a very short version of a text that includes only the most important points from the text. below are two different summaries of the passage you just read. read them both, then answer the question. 1. a 2019 study conducted at the university of arizona in tucson that examined 800 million years of animal diets concluded that the ancestor of all animals was probably a carnivore. the study was probably flawed because it only looked at over 1,000 species of animals currently living, and there are 8.7 million species of animals living today. 2. a 2019 study conducted at the university of arizona in tucson that examined 800 million years of animal diets concluded that the first multicellular animal, the ancestor of all animals, was probably a carnivore that ate protists. a protist is any one - celled organism that is not plant, animal, or fungi. this contradicts earlier studies that concluded the common ancestor of all animals was probably an herbivore. circle the summary that you think is better. why do you think it is better?

Explanation:

Summary 1 is better as it points out the flaw in the study (limited sample size compared to total species) which is an important aspect. Summary 2 adds extra details about protists and contradicts earlier studies but doesn't address the study's limitation which is a key point in evaluating the study's conclusion.

Answer:

Summary 1. It highlights the study's flaw of having a limited sample size, which is crucial in assessing the validity of the conclusion about the animal ancestor's diet.
