Because they were easier to hide than men
<em>“The inflated style itself is a kind of euphemism. A mass of Latin words falls upon the facts like soft snow, blurring the outline and covering up all the details. The great enemy of clear language is insincerity. When there is a gap between one’s real and one’s declared aims, one turns as it were instinctively to long words and exhausted idioms, like a cuttlefish spurting out ink. In our age there is no such thing as ‘keeping out of politics.’ All issues are political issues, and politics itself is a mass of lies, evasions, folly, hatred, and schizophrenia. When the general atmosphere is bad, language must suffer. I should expect to find — this is a guess which I have not sufficient knowledge to verify — that the German, Russian and Italian languages have all deteriorated in the last ten or fifteen years, as a result of dictatorship.”</em>
Sentence 3 supports the main idea of the passage the least because it doesn’t even mention anything about the women in their family, it definitely talks about women and their active ness in politics, but it doesn’t have anything to do with the women in their family whereas all the other sentences do.
