Question

The bar graph below shows the height of a plant at the end of each week of a five-week growth period.

Which statement represents a valid conclusion based on the information in the graph?
1. The plant will grow faster during the sixth week than it did during the fifth week.
2. The plant grew slowest during the first three weeks, and then it grew faster.
3. The plant was given water during the firs three weeks, only.
4. The plant grew fastest during the first three weeks, and then it grew slower.

Answer 1

The most valid conclusion from a plant growth bar graph, where growth rate increases with time, is that the plant grew slowest during the first three weeks and then grew faster. This conclusion is based on the expected trend in plant growth patterns represented in such graphs.

Step-by-step explanation:

The bar graph provided with the question indicates the growth of a plant over a five-week period. To determine which statement represents a valid conclusion based on the provided information, we must look solely at the growth data and avoid making assumptions that are not backed by that data.

The second statement saying the plant grew slowest during the first three weeks, and then it grew faster, seems to match what you would expect from a growth pattern displayed on a typical bar graph: initial slow growth followed by a more rapid phase. This would be a logical conclusion if the bars representing the weekly growth of the plant show an increasing trend in height gain each week after the third week.

Please note that without the actual graph, this conclusion is based on the typical scenario described, and the answer might vary if the graph shows a different growth pattern.
