Problem: Incandescent light bulb:

While inert gas reduces filament evaporation, it also conducts heat from the filament, thereby cooling the filament and reducing efficiency. At constant pressure and temperature, the thermal conductivity of a gas depends upon the molecular weight of the gas and the cross sectional area of the gas molecules. Higher molecular weight gasses have lower thermal conductivity, because both the molecular weight is higher and also the cross sectional area is higher. Xenon gas improves efficiency because of its high molecular weight, but is also more expensive, so its use is limited to smaller lamps.

What conducts heat and heats the filament?

A: unanswerable

Problem: New Zealand has a strong hunting culture. The islands making up New Zealand originally had no land mammals apart from bats. However, once Europeans arrived, game animals were introduced by acclimatisation societies to provide New Zealanders with sport and a hunting resource. Deer, pigs, goats, rabbits, hare, tahr and chamois all adapted well to the New Zealand terrain, and with no natural predators, their population exploded. Government agencies view the animals as pests due to their effects on the natural environment and on agricultural production, but hunters view them as a resource.
Why did the population of pigs and rabbits explode in New Zealand?

Answer: no natural predators

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Generally, American civil procedure has several notable features, including extensive pretrial discovery, heavy reliance on live testimony obtained at deposition or elicited in front of a jury, and aggressive pretrial "law and motion" practice designed to result in a pretrial disposition (that is, summary judgment) or a settlement. U.S. courts pioneered the concept of the opt-out class action, by which the burden falls on class members to notify the court that they do not wish to be bound by the judgment, as opposed to opt-in class actions, where class members must join into the class. Another unique feature is the so-called American Rule under which parties generally bear their own attorneys' fees (as opposed to the English Rule of "loser pays"), though American legislators and courts have carved out numerous exceptions.
What is a pretrial deposition?
A: summary judgment

Context and question: The United Nations Population Fund (UNFPA), formerly the United Nations Fund for Population Activities, is a UN organization. The UNFPA says it "is the lead UN agency for delivering a world where every pregnancy is wanted, every childbirth is safe and every young person's potential is fulfilled." Their work involves the improvement of reproductive health; including creation of national strategies and protocols, and providing supplies and services. The organization has recently been known for its worldwide campaign against obstetric fistula and female genital mutilation.
Where has UNFPA been the most unknown recently?
Answer: unanswerable

Question: Though based upon Mahayana, Tibeto-Mongolian Buddhism is one of the schools that practice Vajrayana or "Diamond Vehicle" (also referred to as Mantrayana, Tantrayana, Tantric Buddhism, or esoteric Buddhism). It accepts all the basic concepts of Mahayana, but also includes a vast array of spiritual and physical techniques designed to enhance Buddhist practice. Tantric Buddhism is largely concerned with ritual and meditative practices. One component of the Vajrayana is harnessing psycho-physical energy through ritual, visualization, physical exercises, and meditation as a means of developing the mind. Using these techniques, it is claimed that a practitioner can achieve Buddhahood in one lifetime, or even as little as three years. In the Tibetan tradition, these practices can include sexual yoga, though only for some very advanced practitioners.
Is there an answer to this question: Psycho-physical energy is harnessed through what?

Answer: ritual

QUES: Although the Catholics and the Orthodox may honor and venerate Mary, they do not view her as divine, nor do they worship her. Roman Catholics view Mary as subordinate to Christ, but uniquely so, in that she is seen as above all other creatures. Similarly Theologian Sergei Bulgakov wrote that the Orthodox view Mary as "superior to all created beings" and "ceaselessly pray for her intercession". However, she is not considered a "substitute for the One Mediator" who is Christ. "Let Mary be in honor, but let worship be given to the Lord", he wrote. Similarly, Catholics do not worship Mary as a divine being, but rather "hyper-venerate" her. In Roman Catholic theology, the term hyperdulia is reserved for Marian veneration, latria for the worship of God, and dulia for the veneration of other saints and angels. The definition of the three level hierarchy of latria, hyperdulia and dulia goes back to the Second Council of Nicaea in 787.

What is the Roman Catholic term used to denote the worship of God?
What is the answer?

latria
