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.
Where did leeches begin being used for blood-letting?
China

Input: Pope Paul VI
On 24 April 2014, it was reported in the Italian magazine Credere that the late pope could possibly be beatified on 19 October 2014. This report from the magazine further stated that several cardinals and bishops would meet on 5 May to confirm the miracle that had previously been approved, and then present it to Pope Francis who may sign the decree for beatification shortly after that. The Congregation for the Causes of Saints held that meeting and positively concluded that the healing was indeed a miracle that could be attributed to the late pope. The matter shall now soon be presented to the pope for approval.

Who needed to approve the Congregation for the Causes of Saints conclusion that Paul VI performed a miracle?

Here is a question about this article: In May 2014, Oklahoma Director of Corrections, Robert Patton, recommended an indefinite hold on executions in the state after the botched execution of African-American Clayton Lockett. The prisoner had to be tasered to restrain him prior to the execution, and the lethal injection missed a vein in his groin, resulting in Lockett regaining consciousness, trying to get up, and to speak, before dying of a heart attack 43 minutes later, after the attempted execution had been called off. In 2015, the state approved nitrogen asphyxiation as a method of execution.
What is the answer to this question: What race was Clayton Lockett?
****
So... African-American

Article: Many insects are considered pests by humans. Insects commonly regarded as pests include those that are parasitic (e.g. lice, bed bugs), transmit diseases (mosquitoes, flies), damage structures (termites), or destroy agricultural goods (locusts, weevils). Many entomologists are involved in various forms of pest control, as in research for companies to produce insecticides, but increasingly rely on methods of biological pest control, or biocontrol. Biocontrol uses one organism to reduce the population density of another organism the pest and is considered a key element of integrated pest management.

Question: What kind of insect can damage architectural structures?
Ans:
termites
