Why does the author refer to the gas mask as “old reliable

Answers

Answer 1

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.

Give an example of what might influence the interpretation of an event.

Answers

Interpretation is defined as a process of the creation of meaning. Life is a series of events, and with each event we attach a meaning . With each event we decide upon an interpretation . It is with these interpretations or attached meanings that we define who and what we are and what we can have and do. Then we go about life collecting evidence to confirm and validate these interpretations . A person's interpretation of an event can be affected through anger , the feeling of being a victim, not making the right decision, negative interpretation and past events among others. That's why it is so important to learn to be in the moment ' in order to experience the genius of you, who you really are, to experience the infinite . No doubt there is a bigger picture out there for your life; it is up to you to master the art of the interpretation

With determination and speed, scientists from the UK, America, and other leading countries created safe and effetive vaccines against Corona. It can be difficult to realize the benefits of being vaccinated amongst the chaos. But in all of human history, no virus that kills so quickly, has been conquered at such a rate. Since the Vaccine was approved, millions have been immunized. Death rates have drastically fallen and global fear is slowly beginning to diminish. Receiving the vaccine will best protect your family and friends. It will reduce the spread of the virus from one person to another. Especially to young children, who at the time are unable to be immunized. Most importantly, it enables individuals to have a lesser chance of falling ill with the Coronavirus.

Which sentence uses correct subject-verb agreement?

B. Flowers on the hillside looks beautiful.
О
C. That cat on the pillows sleep soundly.
D. The party for my parents is coming up soon.

Answers

Answer:

The party for my parents is coming up soon.

Explanation:

--- A is wrong because "students don't runs" they just "run" if it was singular then runs will be correct

--- B is wrong because same reason, you won't say "flowers looks beautiful", you will just say "flowers LOOK beautiful"


---C is also wrong for the exact same reason, since the cat is singular, the verb will have a "s" at the end. so you will say "That cat on the pillows SLEEPS soundly"

D is the only one correct because the party is singular so the verb "is" will also be singular. IF the noun party was changed to parties, then the correct will be "The parties for my parents ARE coming up" but its not

so D is correct because it uses correct subject-verb agreement

Answer:

D. The party for my parents is coming up soon.
