Question: The Ming dynasty granted titles to lamas of schools such as the Karmapa Kargyu, but the latter had previously declined Mongol invitations to receive titles. When the Ming Yongle Emperor invited Je Tsongkhapa (1357–1419), founder of the Gelug school, to come to the Ming court and pay tribute, the latter declined. Wang and Nyima write that this was due to old age and physical weakness, and also because of efforts being made to build three major monasteries. Chen Qingying states that Tsongkhapa wrote a letter to decline the Emperor's invitation, and in this reply, Tsongkhapa wrote:
Is there an answer to this question: The Ming Dynasty granted what titles to lamas of schools?

Answer: the Karmapa Kargyu


Question: Although a resonant antenna has a purely resistive feed-point impedance at a particular frequency, many (if not most) applications require using an antenna over a range of frequencies. An antenna's bandwidth specifies the range of frequencies over which its performance does not suffer due to a poor impedance match. Also in the case of a Yagi-Uda array, the use of the antenna very far away from its design frequency reduces the antenna's directivity, thus reducing the usable bandwidth regardless of impedance matching.
Is there an answer to this question: What term can be used to refer to the usable spectrum of an antennas frequency?

Answer: bandwidth


Question: During a deposition filed for the 1887 trial, Italian inventor Antonio Meucci also claimed to have created the first working model of a telephone in Italy in 1834. In 1886, in the first of three cases in which he was involved, Meucci took the stand as a witness in the hopes of establishing his invention's priority. Meucci's evidence in this case was disputed due to a lack of material evidence for his inventions as his working models were purportedly lost at the laboratory of American District Telegraph (ADT) of New York, which was later incorporated as a subsidiary of Western Union in 1901. Meucci's work, like many other inventors of the period, was based on earlier acoustic principles and despite evidence of earlier experiments, the final case involving Meucci was eventually dropped upon Meucci's death. However, due to the efforts of Congressman Vito Fossella, the U.S. House of Representatives on June 11, 2002 stated that Meucci's "work in the invention of the telephone should be acknowledged", even though this did not put an end to a still contentious issue.[N 17] Some modern scholars do not agree with the claims that Bell's work on the telephone was influenced by Meucci's inventions.[N 18]
Is there an answer to this question: How many court trials did Meucci participate in?

Answer: 3


Question: The use of animal fur in clothing dates to prehistoric times. It is currently associated in developed countries with expensive, designer clothing, although fur is still used by indigenous people in arctic zones and higher elevations for its warmth and protection. Once uncontroversial, it has recently been the focus of campaigns on the grounds that campaigners consider it cruel and unnecessary. PETA, along with other animal rights and animal liberation groups have called attention to fur farming and other practices they consider cruel.
Is there an answer to this question: Who consider animal first to be necessary

Answer:
unanswerable
