Question: The Reinvent the Toilet Challenge is a long-term research and development effort to develop a hygienic, stand-alone toilet. This challenge is being complemented by another investment program to develop new technologies for improved pit latrine emptying (called by the foundation the "Omni-Ingestor") and fecal sludge processing (called "Omni-Processor"). The aim of the "Omni Processor" is to convert excreta (for example fecal sludge) into beneficial products such as energy and soil nutrients with the potential to develop local business and revenue.
Is there an answer to this question: What is another investment program trying to develop?

Answer: unanswerable

Question: However, if the debt rescheduling causes losses on loans held by European banks, it weakens the private banking system, which then puts pressure on the central bank to come to the aid of those banks. Private-sector bond holders are an integral part of the public and private banking system. Another possible response is for wealthy member countries to guarantee or purchase the debt of countries that have defaulted or are likely to default. This alternative requires that the tax revenues and credit of the wealthy member countries be used to refinance the previous borrowing of the weaker member countries, and is politically controversial.
Is there an answer to this question: What happens when the private banking system is gone?

Answer: unanswerable

Question: One example of omnidirectional antennas is the very common vertical antenna or whip antenna consisting of a metal rod (often, but not always, a quarter of a wavelength long). A dipole antenna is similar but consists of two such conductors extending in opposite directions, with a total length that is often, but not always, a half of a wavelength long. Dipoles are typically oriented horizontally in which case they are weakly directional: signals are reasonably well radiated toward or received from all directions with the exception of the direction along the conductor itself; this region is called the antenna blind cone or null.
Is there an answer to this question: What type of antenna would most likely be a half a wavelength long?

Answer:
dipole
