AI Generated Solution

The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Assertion**: The assertion states that in severe cases of pneumonia, the lips and fingernails may turn gray to bluish in color. This phenomenon is known as cyanosis, which occurs when there is insufficient oxygen in the blood. 2. **Understanding the Reason**: The reason provided explains that in pneumonia, the alveoli (the tiny air sacs in the lungs) get filled with fluid, which leads to severe problems in respiration. This fluid accumulation prevents the lungs from filling adequately with air, thereby reducing the amount of oxygen that can be transferred to the bloodstream. 3. **Linking the Assertion and Reason**: The assertion is true because the lack of oxygen in the bloodstream due to pneumonia can cause the skin, lips, and nails to take on a bluish tint. The reason is also true as it accurately describes the physiological process occurring in pneumonia that leads to this condition. 4. **Conclusion**: Since both the assertion and the reason are true, and the reason correctly explains the assertion, we conclude that both statements are valid and related. 5. **Final Answer**: The correct answer is that both the assertion and the reason are true, and the reason is the correct explanation for the assertion. ---

  • Excess inventory, a massive problem for many businesses, has several causes, some of which are unavoidable. Overstocks may accumulate through production overruns or errors. Certain styles and colors prove unpopular. With some products computers and software, toys, and books last year's models are difficult to move even at huge discounts. Occasionally the competition introduces a better product. But in many cases the public's buying tastes simply change, leaving a manufacturer or distributor with thousands (or millions) of items that the fickle public no longer wants. One common way to dispose of this merchandise is to sell it to a liquidator, who buys as cheaply as possible and then resells the merchandise through catalogs, discount stores, and other outlets. However, liquidators may pay less for the merchandise than it cost to make it. Another way to dispose of excess inventory is to dump it. The corporation takes a straight cost write-off on its taxes and hauls the merchandise to a landfill. Although it is hard to believe, there is a sort of convoluted logic to this approach. It is perfectly legal, requires little time or preparation on the company's part, and solves the problem quickly. The draw back is the remote possibility of getting caught by the news media. Dumping perfectly useful products can turn into a public relations nightmare. Children living in poverty are freezing and XYZ Company has just sent 500 new snowsuits to the local dump. Parents of young children are barely getting by and QPS Company dumps 1,000 cases of disposable diapers because they have slight imperfections. The managers of these companies are not deliberately wasteful, they are simply unaware of all their alternatives. In 1976 the Internal Revenue Service provided a tangible incentive for businesses to contribute their products to charity. The new tax law allowed corporations to deduct the cost of the product donated plus half the difference between cost and fair market selling price, with the proviso that deductions cannot exceed twice cost. Thus, the federal government sanctions-indeed, encourages-an above-cost federal tax deduction for companies that donate inventory to charity. In paragraph 3 by asserting that manufacturers "are simply unaware", the author suggests which of the following?

    A
    Manufacturers might donate excess inventory to charity rather than dump it if they knew about the provision in the federal tax code.
    B
    The federal government has failed to provide sufficient encouragement to manufacturers to make use of advantageous tax policies.
    C
    Manufacturers who choose to dump excess inventory are not aware of the possible effects on their reputation of media coverage of such dumping.
    D
    The manufacturers of products disposed of by dumping are unaware of the needs of those people who would find the products useful.
