<p>Polar bears depend on sea ice, which melts during exceptionally warm weather, for access to food. When warm weather lasts longer than normal, polar bears accumulate fat—energy stored for their long winter hibernation—more slowly and weigh less, on average, as a result. At the same time, during periods of prolonged cold, polar bears weigh significantly less than they usually do, on average.p>

<p zoompage-fontsize="16">Many art historians use Roman copies of Greek statues in order to learn more about Greek sculpture. A problem with this strategy is that statues were often adapted from Greek prototypes to suit the taste of Roman patrons. Indeed, these statues often have distinctive features that are not specific to Greek style.p>

<p>Some individuals have an allergic sensitivity to certain proteins, some of which are found in the rubber most often used to make surgical gloves. However, because Manufacturer X does not use those types of rubber in its gloves, individuals who need to use surgical gloves but are allergic to those proteins can use the gloves made by Manufacturer X without risking an allergic reaction.p>

<p>Moon Incorporated produces and distributes the same hubcaps as Sun Incorporated. Steel procurement amounts to about 50 percent of the costs required to produce these hubcaps at both Moon Incorporated and Sun Incorporated. Moon Incorporated is looking to increase its market share at the expense of Sun Incorporated. Thus, pursuant to this end, Moon Incorporated should procure less expensive steel.p>

<p>A likely challenger to Mayor Stephenson in next year’s election has recently stated that the city’s budget is in shambles, citing as evidence the city’s overspending on transportation this year. Portraying the current state of things as intolerable is always in the interest of a challenger to an incumbent, but it is particularly unwarranted in this case. It is true that overspending is generally undesirable, but in this case it was both unavoidable and ultimately advantageous. Failure by past mayors to attend to transportation-infrastructure maintenance forced this administration to make emergency repairs that will lower maintenance and repair costs for the city’s transportation budgets for years to come.p>

<p>A new drug to lower cholesterol has entered the market that, when used in combination with existing drugs called statins, can reduce the risk of heart disease more effectively than statins alone. Patients who tried the new drug in a clinical trial were able to lessen their daily dose of statins without a corresponding increase in blood cholesterol levels. Statins alone, however, cost less, and the money patients saved on statins rarely surpassed the added cost of the new drug. Therefore, for most patients with high cholesterol, adding the new drug to their treatment regimen would be unlikely to lower healthcare costs.p>

This is compelling evidence that intuitive methods should be taught alongside careful step-by-step procedures.p>
