Problem: A look at one minority leadership strategypartisan oppositionmay suggest why it might be employed in specific circumstances. The purposes of obstruction are several, such as frustrating the majority party's ability to govern or attracting press and media attention to the alleged ineffectiveness of the majority party. "We know how to delay," remarked Minority Leader Gephardt Dilatory motions to adjourn, appeals of the presiding officer's ruling, or numerous requests for roll call votes are standard time-consuming parliamentary tactics. By stalling action on the majority party's agenda, the minority leader may be able to launch a campaign against a "do-nothing Congress" and convince enough voters to put his party back in charge of the House. To be sure, the minority leader recognizes that "going negative" carries risks and may not be a winning strategy if his party fails to offer policy alternatives that appeal to broad segments of the general public.
What may be a risk negative tactic?
The answer is the following: if his party fails to offer policy alternatives that appeal to broad segments of the general public

Problem: Gain is a parameter which measures the degree of directivity of the antenna's radiation pattern. A high-gain antenna will radiate most of its power in a particular direction, while a low-gain antenna will radiate over a wider angle. The antenna gain, or power gain of an antenna is defined as the ratio of the intensity (power per unit surface area) radiated by the antenna in the direction of its maximum output, at an arbitrary distance, divided by the intensity radiated at the same distance by a hypothetical isotropic antenna which radiates equal power in all directions. This dimensionless ratio is usually expressed logarithmically in decibels, these units are called "decibels-isotropic" (dBi)
What type of an antenna would offer the same level of power to each possible destination?
The answer is the following: isotropic
