Which ideas from the excerpt would be most appropriate to include in a summary? Select three options. Popular novels from the pa
Leona [9271]

This inquiry lacks completeness due to the missing excerpt; here is the excerpt:

Refer to the segment from President Ronald Reagan’s address the night before the presidential election in 1980.

A well-known book from the 1960s concluded with a foresight about a "kindly, pleasant, greening land recently pondering whether history includes a nation so uniquely characterized by significant ideals and uneasy compromise.” This indeed is the question we face tonight: for the first time many Americans reflect on whether history still accommodates America, her populace, and her grand ideals. Some respond with a "no” saying our energy is depleted, our days of greatness concluded, and that we are experiencing a profound national decline. They propose we lower our expectations, conserve our resources, retreat, and advise our children against dreaming as we once did. I lost a close friend last year, who represented more than just the Hollywood dream; to many, he embodied our nation itself. Upon his passing, the headlines reflected all doubts surrounding America and a longing for a seemingly bygone era. "The Last American Hero," one headline read; another stated, "Mr. America dies.” I was well acquainted with John Wayne, and he would have been offended by being identified as the "last American hero.” Before he passed, he famously remarked, "Just offer the American people a noble pursuit, and there’s nothing they can’t achieve.” Duke Wayne did not perceive our country as nearing the end of its historical significance, and if we contemplate it, we too will recognize it isn’t.

The correct answers are A: Historically significant novels often tackle crucial questions; B: Numerous Americans have resigned themselves believing the nation has lost its greatness; D: Wayne would contest being labeled the last American hero, given that many remain.

Explanation:

To summarize, the summary's objective is to capture essential points that aid in comprehending the subject matter of a text. In the excerpt, President Reagan is questioning if America still holds significance or a role in history. Initially, Reagan points out that this concern arises from a novel from the 1960s, mentioning the question of whether history accommodates a nation composed of significant ideals. Consequently, one essential notion noted is that some novels pose thought-provoking questions relevant today (Option A).

Moreover, Reagan provides two perspectives on this matter. The first revolves around the idea that many believe America's era of greatness has ceased; this is articulated through the statement, "Some say "no”; our energy is exhausted, and the era of greatness has ended" (Option B); the second viewpoint asserts that America is still brimming with greatness and heroic figures, signified by Reagan's reference to Duke Wayne's demise, and the coverage was titled "The Last American Hero"; however, he believes Wayne would fundamentally disagree as he maintained faith in America. Therefore, the third critical detail is captured in option (D).

Brand X Pizza is having a special coupon offer. If you buy two large pizzas, you get $2.00 off the price. A large pizza normally
PIT_PIT [9117]

This is a useful question to answer. I believe there’s not a single place on earth that is free from some form of tax.

Tax is applicable only during transactions where money is exchanged, and it does not affect discounts.

If you decide to take the offer, the cost is determined by:

Cost for two pizzas = standard price - discount applied.

Cost for two pizzas = 2*10.50 - 2.00

Cost for two pizzas = 21 - 2

Cost for two pizzas = 19.00 dollars.

Now, you should add the sales tax to this amount. There are two methods to do this: the detailed method or the quicker method.

Detailed Method

Calculate the sales tax:

Tax = rate * total cost

Tax = (7.5/100) * 19

Tax = 1.425, don’t round yet.

Total Amount = total purchase + tax

Total Amount = 19.00 + 1.425 = 20.425. Now, round it off. The way to round when the last digit is 5 can vary; I usually round up, so my final answer would be 20.43 <<<<< This is the answer.

Quick Method

Final Cost = (Original Price - discount)*(1 + tax rate/100)

Final Cost = (21 - 2)*(1 + 7.5/100)

Final Cost = 19 * (1.075)

Final Cost = 20.425, which rounds to 20.43.
