Problem: Gothic architecture:

The distinctive characteristic of English cathedrals is their extreme length, and their internal emphasis upon the horizontal, which may be emphasised visually as much or more than the vertical lines. Each English cathedral (with the exception of Salisbury) has an extraordinary degree of stylistic diversity, when compared with most French, German and Italian cathedrals. It is not unusual for every part of the building to have been built in a different century and in a different style, with no attempt at creating a stylistic unity. Unlike French cathedrals, English cathedrals sprawl across their sites, with double transepts projecting strongly and Lady Chapels tacked on at a later date, such as at Westminster Abbey. In the west front, the doors are not as significant as in France, the usual congregational entrance being through a side porch. The West window is very large and never a rose, which are reserved for the transept gables. The west front may have two towers like a French Cathedral, or none. There is nearly always a tower at the crossing and it may be very large and surmounted by a spire. The distinctive English east end is square, but it may take a completely different form. Both internally and externally, the stonework is often richly decorated with carvings, particularly the capitals.

What size of cat is typically featured on the west end of English cathedrals?

Problem: Party leaders of the United States House of Representatives:

The current Minority Leader Nancy Pelosi, of the United States House of Representatives serves as floor leader of the opposition party, and is the counterpart to the Majority Leader. Unlike the Majority Leader, the Minority Leader is on the ballot for Speaker of the House during the convening of the Congress. If the Minority Leader's party takes control of the House, and the party officers are all re-elected to their seats, the Minority Leader is usually the party's top choice for Speaker for the next Congress, while the Minority Whip is typically in line to become Majority Leader. The Minority Leader usually meets with the Majority Leader and the Speaker to discuss agreements on controversial issues.

Who does the Minority Whip usually meet with?

A: unanswerable
