Problem: Antenna (radio):

The radiation of many antennas shows a pattern of maxima or "lobes" at various angles, separated by "nulls", angles where the radiation falls to zero. This is because the radio waves emitted by different parts of the antenna typically interfere, causing maxima at angles where the radio waves arrive at distant points in phase, and zero radiation at other angles where the radio waves arrive out of phase. In a directional antenna designed to project radio waves in a particular direction, the lobe in that direction is designed larger than the others and is called the "main lobe". The other lobes usually represent unwanted radiation and are called "sidelobes". The axis through the main lobe is called the "principal axis" or "boresight axis".

What is the main distinction of side lobes?
---
A: represent unwanted radiation

Context and question: About half of the population depends on agriculture (largely subsistence agriculture) for its livelihood, but Namibia must still import some of its food. Although per capita GDP is five times the per capita GDP of Africa's poorest countries, the majority of Namibia's people live in rural areas and exist on a subsistence way of life. Namibia has one of the highest rates of income inequality in the world, due in part to the fact that there is an urban economy and a more rural cash-less economy. The inequality figures thus take into account people who do not actually rely on the formal economy for their survival. Although arable land accounts for only 1% of Namibia, nearly half of the population is employed in agriculture.
How much of the population depends on agriculture?
Answer: half


Question: Prayer plays a significant role among many believers. Muslims believe that the purpose of existence is to worship God. He is viewed as a personal God and there are no intermediaries, such as clergy, to contact God. Prayer often also includes supplication and asking forgiveness. God is often believed to be forgiving. For example, a hadith states God would replace a sinless people with one who sinned but still asked repentance. Christian theologian Alister McGrath writes that there are good reasons to suggest that a "personal god" is integral to the Christian outlook, but that one has to understand it is an analogy. "To say that God is like a person is to affirm the divine ability and willingness to relate to others. This does not imply that God is human, or located at a specific point in the universe."
Is there an answer to this question: What is an example of an intermediary in Islam?

Answer: unanswerable
