Here is a question about this article: One person may presume knowledge of another person's sexual orientation based upon perceived characteristics, such as appearance, clothing, tone of voice, and accompaniment by and behavior with other people. The attempt to detect sexual orientation in social situations is known as gaydar; some studies have found that guesses based on face photos perform better than chance. 2015 research suggests that "gaydar" is an alternate label for using LGBT stereotypes to infer orientation, and that face-shape is not an accurate indication of orientation.
What is the answer to this question: What is a term for someone who tries to determine someones sexuality?

So... gaydar


Here is a question about this article: Carnival in the Netherlands is called Carnaval, Vastenavond or Vastelaovend(j), and is most celebrated in traditionally Catholic regions, mainly the southern provinces North Brabant and Limburg.

Here is a question about this article: The system was later extended to cover larger ranges and some of its practical shortcomings were addressed by the Austrian scientist Josef Maria Eder (1855–1944) and Flemish-born botanist Walter Hecht (de) (1896–1960), (who, in 1919/1920, jointly developed their Eder–Hecht neutral wedge sensitometer measuring emulsion speeds in Eder–Hecht grades). Still, it remained difficult for manufactures to reliably determine film speeds, often only by comparing with competing products, so that an increasing number of modified semi-Scheiner-based systems started to spread, which no longer followed Scheiner's original procedures and thereby defeated the idea of comparability.
What is the answer to this question: What type of measurement methods began to proliferate?

So...
modified semi-Scheiner-based systems
