q... With the scientific data about the health risks of smoking and information about the effect of smoking on troop readiness, in 1975, the United States Department of Defense discontinued the inclusion of cigarettes in K-rations and C-rations. By 1978, the Department of Defense had implemented basic smoking regulations, including the designation of smoking and nonsmoking areas. In 1985, the Department of Defense conducted a study that revealed that smoking rates of military personnel (47 %) were significantly higher than that of US civilians (30 %) and concluded that smoking had a negative effect on troop readiness. The report also cited an estimated tobacco-related healthcare costs as high as $209.9 million, and recommended potential methods to curb smoking in the military, including the elimination of tobacco products from stores, raising tobacco prices to civilian levels, and the implementation of an educational program to discourage smoking. In 1986, the DoD Directive 1010.10 was issued by Secretary of Defense Caspar Weinberger, who announced, "an intense anti-smoking campaign ... at all levels of all Services." It established a policy on smoking and other health risk behaviors such as alcohol consumption. The policy banned the use of tobacco during basic training, increased the number of designated nonsmoking areas, and prohibited health care providers from smoking on duty. The goal of the policy was to reduce all tobacco use rates to below that of civilians, and to reduce personnel and active duty rates from 52 % to 25 % by 1990. In 1992, the DeCA Directive 40-13 policy prohibited commissaries and exchanges from participating with promotions by tobacco manufacturers directed specifically at military personnel, and required commissaries to stock cigarettes in the back. In 1993, the USS Theodore Roosevelt (CVN-71) became the first smoke-free Navy ship. By 1994, the Department of Defense had implemented Directive 1010.15 which banned smoking in workplaces, designated outdoor smoking areas, and created the precursor of an education program that sought to distribute information to new personnel on the health effects of smoking and to encourage smokers to quit. Executive Order 13508 in 1997 banned smoking in all government-owned, rented, or leased interior spaces, but the Department of Defense approved a three-year phase-in period for their facilities and eventually implemented the ban on December 7, 2002. Despite these attempts, by 1988, the smoking rate had only decreased to 42 % and far exceeded the rate of civilians. And although prevalence did decrease to 29.9 % from 1980 to 1998, it has increased since then and appears to still be increasing.

q... Context: The Tomb of Ghiyas ud din Balban is located in Mehrauli, New Delhi, India. Built in circa 1287 CE in rubble masonry, the tomb is a building of historical importance in the development of Indo-Islamic architecture, as it was here that first true arch made its appearance in India, and according to many, the first true dome as well, which however has n't survived, making Alai Darwaza built in 1311 CE, in the nearby Qutb complex, the earliest surviving true dome in India. Ghiyas ud din Balban (1200 -- 1287) was a Turkic ruler of the Delhi Sultanate during the rule of Mamluk dynasty of Delhi (or Slave dynasty) from 1266 to 1287. He was one of the most prominent rulers of the Slave Dynasty. The tomb of Balban was discovered in the mid-twentieth century.

Question: the earliest surviving building in india containing a true dome is?

The relevant sentence in the passage is: Built in circa 1287 CE in rubble masonry, the tomb is a building of historical importance in the development of Indo-Islamic architecture, as it was here that first true arch made its appearance in India, and according to many, the first true dome as well, which however has n't survived, making Alai Darwaza built in 1311 CE, in the nearby Qutb complex, the earliest surviving true dome in India.
The answer is Alai Darwaza

q... An antibody (Ab), also known as an immunoglobulin (Ig), is a large, Y-shaped protein produced mainly by plasma cells that is used by the immune system to neutralize pathogens such as pathogenic bacteria and viruses. The antibody recognizes a unique molecule of the pathogen, called an antigen, via the Fab's variable region. Each tip of the "Y" of an antibody contains a paratope (analogous to a lock) that is specific for one particular epitope (similarly analogous to a key) on an antigen, allowing these two structures to bind together with precision. Using this binding mechanism, an antibody can tag a microbe or an infected cell for attack by other parts of the immune system, or can neutralize its target directly (for example, by blocking a part of a microbe that is essential for its invasion and survival). Depending on the antigen, the binding may impede the biological process causing the disease or may activate macrophages to destroy the foreign substance. The ability of an antibody to communicate with the other components of the immune system is mediated via its Fc region (located at the base of the "Y"), which contains a conserved glycosylation site involved in these interactions. The production of antibodies is the main function of the humoral immune system.

Based on this passage, what is the role of antibodies in the immune response?
a...
