Input: Article: The older 78 format continued to be mass-produced alongside the newer formats using new materials until about 1960 in the U.S., and in a few countries, such as India (where some Beatles recordings were issued on 78), into the 1960s. For example, Columbia Records' last reissue of Frank Sinatra songs on 78 rpm records was an album called Young at Heart, issued November 1, 1954. As late as the 1970s, some children's records were released at the 78 rpm speed. In the United Kingdom, the 78 rpm single lasted longer than in the United States and the 45 rpm took longer to become popular. The 78 rpm was overtaken in popularity by the 45 rpm in the late 1950s, as teenagers became increasingly affluent.

Now answer this question: At which time were the 79 rpm no longer mass produced?

Output: about 1960

Here is a question about this article: Unlike other European nations, the Dutch chose not to follow a policy of language expansion amongst the indigenous peoples of their colonies. In the last quarter of the 19th century, however, a local elite gained proficiency in Dutch so as to meet the needs of expanding bureaucracy and business. Nevertheless, the Dutch government remained reluctant to teach Dutch on a large scale for fear of destabilising the colony. Dutch, the language of power, was supposed to remain in the hands of the leading elite.
What is the answer to this question: What VIP segment of the population in Dutch colonies learned Dutch to participate in business and government?
****
So... local elite

Problem: Please answer a question about the following article about Biodiversity:
Global agreements such as the Convention on Biological Diversity, give "sovereign national rights over biological resources" (not property). The agreements commit countries to "conserve biodiversity", "develop resources for sustainability" and "share the benefits" resulting from their use. Biodiverse countries that allow bioprospecting or collection of natural products, expect a share of the benefits rather than allowing the individual or institution that discovers/exploits the resource to capture them privately. Bioprospecting can become a type of biopiracy when such principles are not respected.[citation needed]
What agreement commits countries to develop resources for sustainability?
A: the Convention on Biological Diversity

Question: Read this and answer the question

Bacteria were first observed by the Dutch microscopist Antonie van Leeuwenhoek in 1676, using a single-lens microscope of his own design. He then published his observations in a series of letters to the Royal Society of London. Bacteria were Leeuwenhoek's most remarkable microscopic discovery. They were just at the limit of what his simple lenses could make out and, in one of the most striking hiatuses in the history of science, no one else would see them again for over a century. Only then were his by-then-largely-forgotten observations of bacteria as opposed to his famous "animalcules" (spermatozoa) taken seriously.

How was he able to see bacteria?
Answer:
using a single-lens microscope of his own design
