[Q]: Extract the answer to the question from the following context. Question: When, if ever, were both of the Americas connected? Context: In many ways, the Paleocene continued processes that had begun during the late Cretaceous Period. During the Paleocene, the continents continued to drift toward their present positions. Supercontinent Laurasia had not yet separated into three continents. Europe and Greenland were still connected. North America and Asia were still intermittently joined by a land bridge, while Greenland and North America were beginning to separate. The Laramide orogeny of the late Cretaceous continued to uplift the Rocky Mountains in the American west, which ended in the succeeding epoch. South and North America remained separated by equatorial seas (they joined during the Neogene); the components of the former southern supercontinent Gondwana continued to split apart, with Africa, South America, Antarctica and Australia pulling away from each other. Africa was heading north toward Europe, slowly closing the Tethys Ocean, and India began its migration to Asia that would lead to a tectonic collision and the formation of the Himalayas.

[A]: during the Neogene

[Q]: Extract the answer to the question from the following context. Question: What was the job of people using the new guns? Context: After the Dambusters raid in 1943 an entirely new system was developed that was required to knock down any low-flying aircraft with a single hit. The first attempt to produce such a system used a 50 mm gun, but this proved inaccurate and a new 55 mm gun replaced it. The system used a centralised control system including both search and targeting radar, which calculated the aim point for the guns after considering windage and ballistics, and then sent electrical commands to the guns, which used hydraulics to point themselves at high speeds. Operators simply fed the guns and selected the targets. This system, modern even by today's standards, was in late development when the war ended.
****
[A]: fed the guns and selected the targets

[Q]: Extract the answer to the question from the following context. Question: What can a canine's olfactory glands do? Context: Anthropologists believe the most significant benefit would have been the use of dogs' robust sense of smell to assist with the hunt. The relationship between the presence of a dog and success in the hunt is often mentioned as a primary reason for the domestication of the wolf, and a 2004 study of hunter groups with and without a dog gives quantitative support to the hypothesis that the benefits of cooperative hunting was an important factor in wolf domestication.
****
[A]: assist with the hunt

[Q]: Extract the answer to the question from the following context. Question: Which of the following words is in English: dhikr, tanzil, or revelation? Context: The term also has closely related synonyms that are employed throughout the Quran. Each synonym possesses its own distinct meaning, but its use may converge with that of qur'an in certain contexts. Such terms include kitab (book); ayah (sign); and surah (scripture). The latter two terms also denote units of revelation. In the large majority of contexts, usually with a definite article (al-), the word is referred to as the "revelation" (wahy), that which has been "sent down" (tanzil) at intervals. Other related words are: dhikr (remembrance), used to refer to the Quran in the sense of a reminder and warning, and hikmah (wisdom), sometimes referring to the revelation or part of it.
