Article: The city slopes gently from the northwest to southeast on a till plain composed largely of glacial and lake clay. The most notable topographical feature in the city is the Detroit Moraine, a broad clay ridge on which the older portions of Detroit and Windsor sit atop, rising approximately 62 feet (19 m) above the river at its highest point. The highest elevation in the city is located directly north of Gorham Playground on the northwest side approximately three blocks south of 8 Mile Road, at a height of 675 to 680 feet (206 to 207 m). Detroit's lowest elevation is along the Detroit River, at a surface height of 572 feet (174 m).

Here is a question about this article: The Roman Empire reached its greatest territorial extent during the 2nd century AD; the following two centuries witnessed the slow decline of Roman control over its outlying territories. Economic issues, including inflation, and external pressure on the frontiers combined to make the 3rd century politically unstable, with emperors coming to the throne only to be rapidly replaced by new usurpers. Military expenses increased steadily during the 3rd century, mainly in response to the war with Sassanid Persia, which revived in the middle of the 3rd century. The army doubled in size, and cavalry and smaller units replaced the legion as the main tactical unit. The need for revenue led to increased taxes and a decline in numbers of the curial, or landowning, class, and decreasing numbers of them willing to shoulder the burdens of holding office in their native towns. More bureaucrats were needed in the central administration to deal with the needs of the army, which led to complaints from civilians that there were more tax-collectors in the empire than tax-payers.
What is the answer to this question: In what century did the Roman Empire achieve its greatest extent?
****
So... the 2nd century AD


The problem: Answer a question about this article:
Several dozen radioisotopes have been characterized. 65Zn, which has a half-life of 243.66 days, is the most long-lived radioisotope, followed by 72Zn with a half-life of 46.5 hours. Zinc has 10 nuclear isomers. 69mZn has the longest half-life, 13.76 h. The superscript m indicates a metastable isotope. The nucleus of a metastable isotope is in an excited state and will return to the ground state by emitting a photon in the form of a gamma ray. 61Zn has three excited states and 73Zn has two. The isotopes 65Zn, 71Zn, 77Zn and 78Zn each have only one excited state.
What is the most long lived radio isotope?
****
The answer: 65Zn


The problem: Answer a question about this article:
These categories are aspects of the more nuanced nature of sexual identity and terminology. For example, people may use other labels, such as pansexual or polysexual, or none at all. According to the American Psychological Association, sexual orientation "also refers to a person's sense of identity based on those attractions, related behaviors, and membership in a community of others who share those attractions". Androphilia and gynephilia are terms used in behavioral science to describe sexual orientation as an alternative to a gender binary conceptualization. Androphilia describes sexual attraction to masculinity; gynephilia describes the sexual attraction to femininity. The term sexual preference largely overlaps with sexual orientation, but is generally distinguished in psychological research. A person who identifies as bisexual, for example, may sexually prefer one sex over the other. Sexual preference may also suggest a degree of voluntary choice, whereas the scientific consensus is that sexual orientation is not a choice.
What terms does behavorial science use instead of using gender binary conceptualization?
****
The answer:
Androphilia and gynephilia
