https://gmatclub.com/forum/download/file.php?id=82905 A wildlife conservation program is monitoring the weight and height of different species of birds in preparation for their seasonal migration. The chart displays the maximum and minimum weights for birds across different heights to ensure a successful migration. Select from each drop-down menu the option that creates the most accurate statement, given the information provided. In order to ensure successful migration, a bird with a height of 64 centimeters should weigh at least GRAPH_1_PLACEHOLDER kilograms, which is approximately GRAPH_2_PLACEHOLDER kilograms less than the maximum weight of birds of the same height.

Official Solution:

To find the minimum weight required for a bird that is 64 centimeters tall, locate 64 on the x-axis and read the corresponding value from the lower curve (minimum weight). This value is approximately 5.1 kilograms.
 
Next, to determine how much less this is than the maximum weight for birds of the same height, find the value on the upper curve at 64 centimeters. This is approximately 5.3 kilograms. The difference is 5.3 − 5.1 = 0.2 kilograms.

Correct answer:

Dropdown 1:  "5.1"

Dropdown 2:  "0.2"

Here is the official solution:

A bird with a height of 64 centimeters should weigh at least (minimum weight): 
 
 From the chart, at 64 cm height, the minimum weight is approximately  5.1 kg.   
 The max weight of birds of the same height is approximately: 
 
 The maximum weight for birds of 64 cm height is about  5.3 kg.   
 The difference between max and minimum weight: 
 
 The difference between max (5.3 kg) and minimum (5.1kg) is  0.2kg

1. We're interested about the weight of a bird with a height of 64 cm. A vertical line can be drawn at 64.

2. First, the question asks us the minimum weight. To find this, we can look at the y-value of the intersection between the line at 64 cm and the minimum graph. This is around 5.1 kg.

3. Next, we need to find the difference between the minimum and maximum weights. The maximum weight is the y-value of the intersection between the line at 64 cm and the maximum graph. This is around 5.3 kg. The difference is 5.3 kg - 5.1 kg = 0.2 kg.

4. Our answer will be:   D1 - 5.1 and D2 - 0.2  .
