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

When the Majority Leader's party loses control of the House, and if the Speaker and Majority Leader both remain in the leadership hierarchy, convention suggests that they would become the Minority Leader and Minority Whip, respectively. As the minority party has one less leadership position after losing the speaker's chair, there may be a contest for the remaining leadership positions. Nancy Pelosi is the most recent example of an outgoing Speaker seeking the Minority Leader post to retain the House party leadership, as the Democrats lost control of the House in the 2010 elections. Outgoing Speaker Nancy Pelosi ran successfully for Minority Leader in the 112th Congress.

Does the minority or majority party have more leadership positions in House?
---
A: minority party has one less leadership position

Problem: The fossil record suggests that the last few million years featured the greatest biodiversity in history. However, not all scientists support this view, since there is uncertainty as to how strongly the fossil record is biased by the greater availability and preservation of recent geologic sections. Some scientists believe that corrected for sampling artifacts, modern biodiversity may not be much different from biodiversity 300 million years ago., whereas others consider the fossil record reasonably reflective of the diversification of life. Estimates of the present global macroscopic species diversity vary from 2 million to 100 million, with a best estimate of somewhere near 9 million, the vast majority arthropods. Diversity appears to increase continually in the absence of natural selection.
Why are some scientists uncertain about the fossil record?

Answer: how strongly the fossil record is biased by the greater availability and preservation of recent geologic sections.

In contrast, the police are entitled to protect private rights in some jurisdictions. To ensure that the police would not interfere in the regular competencies of the courts of law, some police acts require that the police may only interfere in such cases where protection from courts cannot be obtained in time, and where, without interference of the police, the realization of the private right would be impeded. This would, for example, allow police to establish a restaurant guest's identity and forward it to the innkeeper in a case where the guest cannot pay the bill at nighttime because his wallet had just been stolen from the restaurant table.
What couldn't be impeded without police interference?
A: unanswerable

Sextus Julius Africanus further refers to the writings of historian Thallus: "This darkness Thallus, in the third book of his History, calls, as appears to me without reason, an eclipse of the sun.

Christian apologist Tertullian believed the event was documented in the Roman archives.
His book of History was Tertullian's what in a series of books written?
