Question

review the text. the amazon river basin is home to several species of river dolphins, also called botos. in 2014, a group of scientists headed by biologist tomas hrbek published a study announcing the discovery of a new river dolphin species. the study concluded that dolphins found in the araguaia river in brazil are distinct from their cousins elsewhere in the amazon. the araguaian botos share some characteristics with other amazon dolphins, like a long, toothy beak and pink - gray skin. however, araguaian botos appear to have a different number of teeth, unique skull features, and slightly different dna. not everyone is convinced, though. hrbeks team could examine only a few animals, and critics argue that more specimens need to be studied. if the studys findings are confirmed, however, the araguaian boto would be the first new river dolphin species discovered in almost a hundred years! which best shows that the authors purpose is to inform readers about the possible discovery of a new river dolphin species in the amazon? the author describes the characteristics of amazon dolphins, such as pink - gray skin. the author provides facts about the study, including when it was published and what it shows about araguaian dolphins. the author creates excitement around the fact that the discovery could be the first one in almost a hundred years.

Explanation:

To inform, an author presents facts. The dates of study - publication and details about Araguaian dolphins from the study are facts. Describing general Amazon dolphin characteristics is less directly related to the new - species discovery. Creating excitement is more about evoking emotion than pure information - giving.

Answer:

The author provides facts about the study, including when it was published and what it shows about Araguaian dolphins.
