Question

1. the rabbit population in the year 1997 is closest to....

rabbit population growth from 1992-2012
chart: y-axis (number of individuals (millions)) with values 0, 0.05, 0.1, 0.15, 0.2, 0.25, 0.3, 0.35, 0.4, 0.45, 0.5; x-axis (year) with 1992, 1997, 2002, 2007, 2012
options:
○ 15 million
○ 0.15 million
○ 0.15
○ 19 million
○ 0.19 million
○ 25
○ 25 million

Explanation:

Step1: Analyze the graph's y - axis

The y - axis of the graph is labeled "Number of individuals (millions)". So we are looking for a value in millions. We can eliminate options like "0.15" and "25" (since 25 has no unit of millions and 0.15 is just a number without the million unit as per the context of the graph's y - axis). Also, 15 million and 19 million seem too large as the graph's y - axis only goes up to 0.5 million.

Step2: Locate 1997 on the x - axis

Looking at the graph, for the year 1997, we check the corresponding point on the y - axis. The point for 1997 is around 0.15 million (since the y - axis values are in millions and the value at 1997 is close to 0.15 on the y - axis scale which is in millions). Let's check the options:

• 15 million: Too large, the graph's max y - value is 0.5 million.
• 0.15 million: Matches the scale (y - axis in millions) and the position of 1997 on the graph.
• 0.15: No unit of millions, incorrect.
• 19 million: Too large.
• 0.19 million: The value at 1997 is closer to 0.15 million than 0.19 million.
• 25: No unit, incorrect.
• 25 million: Too large.

Answer:

0.15 million
