Article: Gain is a parameter which measures the degree of directivity of the antenna's radiation pattern. A high-gain antenna will radiate most of its power in a particular direction, while a low-gain antenna will radiate over a wider angle. The antenna gain, or power gain of an antenna is defined as the ratio of the intensity (power per unit surface area) radiated by the antenna in the direction of its maximum output, at an arbitrary distance, divided by the intensity radiated at the same distance by a hypothetical isotropic antenna which radiates equal power in all directions. This dimensionless ratio is usually expressed logarithmically in decibels, these units are called "decibels-isotropic" (dBi)

Question: What is another way to refer to an antennas gain?
Ans: power gain

Here is a question about this article: Accounts of the use of leeches for the medically dubious practise of blood-letting have come from China around 30 AD, India around 200 AD, ancient Rome around 50 AD and later throughout Europe. In the 19th century medical demand for leeches was so high that some areas' stocks were exhausted and other regions imposed restrictions or bans on exports, and Hirudo medicinalis is treated as an endangered species by both IUCN and CITES. More recently leeches have been used to assist in microsurgery, and their saliva has provided anti-inflammatory compounds and several important anticoagulants, one of which also prevents tumors from spreading.
What is the answer to this question: When did India begin using leeches?
****
So... 200 AD

Some breeds of dogs are prone to certain genetic ailments such as elbow and hip dysplasia, blindness, deafness, pulmonic stenosis, cleft palate, and trick knees. Two serious medical conditions particularly affecting dogs are pyometra, affecting unspayed females of all types and ages, and bloat, which affects the larger breeds or deep-chested dogs. Both of these are acute conditions, and can kill rapidly. Dogs are also susceptible to parasites such as fleas, ticks, and mites, as well as hookworms, tapeworms, roundworms, and heartworms.
What are all dogs susceptible to?
****
The answer: parasites

Problem: Please answer a question about the following article about Religion in ancient Rome:
Funeral and commemorative rites varied according to wealth, status and religious context. In Cicero's time, the better-off sacrificed a sow at the funeral pyre before cremation. The dead consumed their portion in the flames of the pyre, Ceres her portion through the flame of her altar, and the family at the site of the cremation. For the less well-off, inhumation with "a libation of wine, incense, and fruit or crops was sufficient". Ceres functioned as an intermediary between the realms of the living and the dead: the deceased had not yet fully passed to the world of the dead and could share a last meal with the living. The ashes (or body) were entombed or buried. On the eighth day of mourning, the family offered further sacrifice, this time on the ground; the shade of the departed was assumed to have passed entirely into the underworld. They had become one of the di Manes, who were collectively celebrated and appeased at the Parentalia, a multi-day festival of remembrance in February.
What was the grave sacrifice in Cicero's time?
A: sow

The body's capability to react to antigen depends on a person's age, antigen type, maternal factors and the area where the antigen is presented. Neonates are said to be in a state of physiological immunodeficiency, because both their innate and adaptive immunological responses are greatly suppressed. Once born, a child's immune system responds favorably to protein antigens while not as well to glycoproteins and polysaccharides. In fact, many of the infections acquired by neonates are caused by low virulence organisms like Staphylococcus and Pseudomonas. In neonates, opsonic activity and the ability to activate the complement cascade is very limited. For example, the mean level of C3 in a newborn is approximately 65% of that found in the adult. Phagocytic activity is also greatly impaired in newborns. This is due to lower opsonic activity, as well as diminished up-regulation of integrin and selectin receptors, which limit the ability of neutrophils to interact with adhesion molecules in the endothelium. Their monocytes are slow and have a reduced ATP production, which also limits the newborn's phagocytic activity. Although, the number of total lymphocytes is significantly higher than in adults, the cellular and humoral immunity is also impaired. Antigen-presenting cells in newborns have a reduced capability to activate T cells. Also, T cells of a newborn proliferate poorly and produce very small amounts of cytokines like IL-2, IL-4, IL-5, IL-12, and IFN-g which limits their capacity to activate the humoral response as well as the phagocitic activity of macrophage. B cells develop early during gestation but are not fully active.

Antigen cells in newborns are also struggle to do this?
Answer: activate T cells

From childhood, Gaddafi was aware of the involvement of European colonialists in Libya; his nation was occupied by Italy, and during the North African Campaign of World War II it witnessed conflict between Italian and British troops. According to later claims, Gaddafi's paternal grandfather, Abdessalam Bouminyar, was killed by the Italian Army during the Italian invasion of 1911. At World War II's end in 1945, Libya was occupied by British and French forces. Although Britain and France intended on dividing the nation between their empires, the General Assembly of the United Nations (UN) declared that the country be granted political independence. In 1951, the UN created the United Kingdom of Libya, a federal state under the leadership of a pro-western monarch, Idris, who banned political parties and established an absolute monarchy.
What countries occupied Libya after World War II?
British and French forces
