Question

what evidence from \conservation as a national duty\ most effectively establishes that roosevelt’s speech is structured to bring attention to an issue and make a call to action for change? select all that apply. conservation as a national duty with the rise of peoples from savagery to civilization, and with the consequent growth in the extent and variety of the needs of the average man, there comes a steadily increasing growth of the amount demanded by this average man from the actual resources of the country i have asked you to come together now because the enormous consumption of these resources, and the threat of imminent exhaustion of some of them, due to reckless and wasteful use, once more calls for common effort, common action. this conference on the conservation of natural resources is in effect a meeting of the representatives of all the people of the united states called to consider the weightiest problem now before the nation, and the occasion for the meeting lies in the fact that the natural resources of our country are in danger of exhaustion if we permit the old wasteful methods of exploiting them longer to continue now, i ask you to think what that means, and i am speaking with historic literalness. in the development, the use, and therefore the exhaustion of certain of the natural resources, the progress has been more rapid in the past century and a quarter than during all preceding time of which we have record.

Explanation:

1. For the second option: The sentence "I have asked you to come together now because the enormous consumption of these resources, and the threat of imminent exhaustion of some of them, due to reckless and wasteful use, once more calls for common effort, common action" directly states the issue (resource consumption and threat of exhaustion) and makes a call to action (common effort, common action).
2. For the third option: "This Conference on the conservation of natural resources is in effect a meeting of the representatives of all the people of the United States called to consider the weightiest problem now before the Nation, and the occasion for the meeting lies in the fact that the natural resources of our country are in danger of exhaustion if we permit the old wasteful methods of exploiting them longer to continue" presents the issue (natural resources in danger of exhaustion) and implies a call to action by convening a conference to address it.

The first option only describes the growth of resource demand, not a call to action. The fourth option focuses on the rapid progress of resource exhaustion, not a call to action.

Answer:

B. I have asked you to come together now because the enormous consumption of these resources, and the threat of imminent exhaustion of some of them, due to reckless and wasteful use, once more calls for common effort, common action
