Answer (2)
Analyze the casualty data for each country: Great Britain, Germany, France, and the United States.
Compare the total casualties across the countries to determine which country suffered the most.
Evaluate each conclusion based on the data in the table.
Conclude that the war resulted in many casualties for all of the countries that participated. b o x e d The war resulted in many casualties for all of the countries that participated.
Explanation
Problem Analysis We are given a table showing the military casualties of World War I for Great Britain, Germany, France, and the United States. The table includes the number of soldiers killed, soldiers wounded, and the total number of casualties for each country. We need to determine which conclusion can be drawn from the data provided in the table.
Analyzing the Conclusions Let's analyze each of the given conclusions:
'The number of casualties were small compared to the size of the countries involved.'
This statement is subjective and requires additional information about the population sizes of the countries involved. We cannot determine this from the given data alone.
'France suffered the greatest number of casualties because it did the most fighting.'
We need to check if France had the greatest number of total casualties. From the table, France had 6,160,000 casualties. We need to compare this to the other countries.
'The war resulted in many casualties for all of the countries that participated.'
We need to assess if the numbers in the 'All Casualties' column are considered 'many'.
'Great Britain had the greatest number of casualties because if fought the longest.'
We need to check if Great Britain had the greatest number of total casualties. From the table, Great Britain had 3,190,225 casualties. We need to compare this to the other countries.
Comparing Total Casualties Now, let's compare the total casualties for each country:
Great Britain: 3,190,225
Germany: 7,142,559
France: 6,160,000
United States: 323,018
From this, we can see that Germany had the greatest number of casualties, followed by France. Great Britain had fewer casualties than both Germany and France. The United States had the fewest casualties.
Evaluating the Conclusions Based on the comparison, we can evaluate the conclusions:
'The number of casualties were small compared to the size of the countries involved.' - Cannot be determined from the data.
'France suffered the greatest number of casualties because it did the most fighting.' - This is incorrect, as Germany had the greatest number of casualties.
'The war resulted in many casualties for all of the countries that participated.' - This is a reasonable conclusion, as the numbers of casualties for Great Britain, Germany, and France are all very large.
'Great Britain had the greatest number of casualties because if fought the longest.' - This is incorrect, as Germany had the greatest number of casualties.
Final Answer Therefore, the most accurate conclusion that can be drawn from the chart is: 'The war resulted in many casualties for all of the countries that participated.'
Summary The correct conclusion is that the war resulted in many casualties for all of the countries that participated.
Examples
Understanding the scale of casualties in historical events like World War I helps us appreciate the human cost of conflict. For example, if you're studying the impact of different military strategies or the effectiveness of medical advancements during the war, knowing the casualty numbers provides a stark measure of the war's devastation. This data can also be used to inform discussions on international relations and the importance of peaceful conflict resolution. Imagine you are a historian analyzing the impact of WWI, the casualty data helps you understand the scale of loss and its long-term effects on the involved nations. The data from the table emphasizes the importance of understanding the consequences of war and promoting peace.
Approximately 2.81 × 1 0 21 electrons flow through an electric device when it delivers a current of 15.0 A for 30 seconds. This is calculated using the relationship between current, charge, and the charge of a single electron. The charge flowing through can be derived using the formula Q = I × t .
