Answer: Where is the information?
Answer:
This American myth has taken root in classrooms across the country, where children are being encouraged to create their own "quilt codes" and believe fictional stories as if they reflect proven fact.
Explanation:
The idea in sentence 2 states that there was no historical evidence to show that quilts which were hung on clotheslines were in fact used as secret codes by travelers on the Underground Railway and the sentence that develops this idea is the sentence that says that children in schools are encouraged to to create their own quilt codes and stating that they fictional events as if they were real.
used in the 1970s and 1980s
Airborne toxic materials may be gaseous (for example, mustard gas and chlorine gas) or particulates (such as biological agents). Many filters include protection from both types.
The first gas masks mostly used circular lenses made either of glass, mica or cellulose acetate. With the exception of the latter, these materials were quite brittle and needed frequent replacement. Later on, the Triplex lens style (two layers of glass and one layer of cellulose acetate in between)[1] became more popular, and alongside the simpler cellulose acetate they became the standard into the 1930s. Panoramic lenses were not popular until the 1930s, but there are some examples of those being used even during the war (Austro-Hungarian 15M). Later, polycarbonate started being used for its strength.
Some have one or two filters screwed (via inlets) onto to the gas mask while others have a large filter (coffee can filter) connected to the gas mask with a hose that is sometimes confused with an air-supplied respirator in which an alternate supply of fresh air (oxygen tanks) is delivered.
