TASK DEFINITION: This task is about reading the given passage and construct a question about the information present in the passage. Construct a question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) its answer is a continuous text span from the paragraph. Avoid creating questions that (i) can be answered correctly without actually understanding the paragraph and (ii) uses same words or phrases given in the passage.
PROBLEM: The roots of Presbyterianism lie in the European Reformation of the 16th century; the example of John Calvin's Geneva being particularly influential. Most Reformed churches which trace their history back to Scotland are either presbyterian or congregationalist in government. In the twentieth century, some Presbyterians played an important role in the ecumenical movement, including the World Council of Churches. Many Presbyterian denominations have found ways of working together with other Reformed denominations and Christians of other traditions, especially in the World Communion of Reformed Churches. Some Presbyterian churches have entered into unions with other churches, such as Congregationalists, Lutherans, Anglicans, and Methodists. Presbyterians in the United States came largely from Scotch-Irish immigrants communities, and also from New England Yankee communities that had originally been Congregational but changed because of an agreed-upon "Plan of Union of 1801" for frontier areas.

SOLUTION: Where do most presbyterian churches trace their history back to?

PROBLEM: The style and role of any minority leader is influenced by a variety of elements, including personality and contextual factors, such as the size and cohesion of the minority party, whether his or her party controls the White House, the general political climate in the House, and the controversy that is sometimes associated with the legislative agenda. Despite the variability of these factors, there are a number of institutional obligations associated with this position. Many of these assignments or roles are spelled out in the House rule book. Others have devolved upon the position in other ways. To be sure, the minority leader is provided with extra staff resources—beyond those accorded him or her as a Representative—to assist in carrying out diverse leadership functions. Worth emphasis is that there are limits on the institutional role of the minority leader, because the majority party exercises disproportionate influence over the agenda, partisan ratios on committees, staff resources, administrative operations, and the day-to-day schedule and management of floor activities.

SOLUTION: How is the minority leader able to accomplish addition demands and tasks?

PROBLEM: This is fortunate, since antennas at lower frequencies which are not rather large (a good fraction of a wavelength in size) are inevitably inefficient (due to the small radiation resistance Rr of small antennas). Most AM broadcast radios (except for car radios) take advantage of this principle by including a small loop antenna for reception which has an extremely poor efficiency. Using such an inefficient antenna at this low frequency (530–1650 kHz) thus has little effect on the receiver's net performance, but simply requires greater amplification by the receiver's electronics. Contrast this tiny component to the massive and very tall towers used at AM broadcast stations for transmitting at the very same frequency, where every percentage point of reduced antenna efficiency entails a substantial cost.

SOLUTION:
Small and minimal frequency antennas are know to be what?
