Question 25·Easy·Command of Evidence
Recordings of Female Bottlenose Dolphins with Their Calves
| Dolphin ID | Recording year |
|---|---|
| FB07 | 2012 |
| FB25 | 1989 |
| FB43 | 1992 |
| FB79 | 2018 |
In a study of bottlenose dolphins, biologist Laela S. Sayigh and a team of researchers analyzed recordings of female bottlenose dolphins interacting with their calves.
According to the table, in which year was the dolphin with the ID FB43 recorded with her calf?
For questions that use tables or charts, start by underlining what the question is asking for (here, the recording year for a specific ID). Then, go straight to the relevant row or column—first find the correct label (FB43), then read across or down to the needed value. Finally, match that value exactly to one of the answer choices, ignoring any years or data that belong to other rows.
Hints
Use the column labels
Pay attention to the column titles: one column shows the dolphin ID and the other shows the recording year. You need both to answer the question.
Find the correct row first
In the "Dolphin ID" column, find the row where the ID is FB43. Only information from that row will help you answer the question.
Then read across to the year
Once you’ve found FB43, move straight across to the "Recording year" column and use that year to choose among the options.
Step-by-step Explanation
Locate the correct dolphin ID in the table
Look at the first column labeled "Dolphin ID" and scan down the list (FB07, FB25, FB43, FB79) until you find the row with ID FB43.
Read the recording year for FB43
Stay on the same row as FB43 and move your eyes to the right, into the "Recording year" column. Note the year listed there.
Match the year to an answer choice
Take the recording year you found in the FB43 row and compare it with the answer choices (1999, 2012, 2020, 1992). The year that matches the table for FB43 is 1992, so choice D) 1992 is correct.
