They do means test it. The rate of "return" is higher the lower your AIME.

The cap has been increased several times.

I'd bet people becoming more liberal than age stems from a) a more polarized electorate and b) what it means to be liberal being expanded.

That is done by reducing viral load. They also didn't claim it stopped all infection, but reducing probability of infection has the effect of reducing infections.

Gender in grammar is just another dimension to word, like case, number or tense. It isn't even necessarily masculine or feminine. German has a neuter gender as well; Arabic has a two level gender system with masculine/feminine and animate/inanimate. Dravidian languages have genders that distinguish a noun between human and non-human classifications.

Grammatical gender largely serves to distinguish the antecedents of pronouns in the same sentence through agreement with other words. It isn't necessary for a language to function(only 25% or so of languages have it), but adds granularity with fewer words.

The reason people who gender a particular noun masculine in one language are put off by them being gendered grammatically feminine in another isn't because of bias for or against one sex, but the normal jarring effect of differences in syntax. Some languages have different rules for apposition that mess with you, and some languages have different rules for whether an adjective for a noun follows or precedes the noun to which it applies, or whether there's agreement in number or not.

English is a particular one of confusion for non native speakers because it's a Germanic language with a simplified Germanic grammar structure(absent grammatical gender and noun declension) but has tons of French loanwords and cognates that brings with them French syntaxes and orthographies(German doesn't have silent letters for example)

And women are seen as more human.

Boats being gendered has more to do with arbitrary grammatical gender.

That's the point. You can't really, but doing a "study" makes it seek like there's a rigor to examining it.

Lions aren't even kings of the jungle. Tigers are more likely.

RO systems overcome osmotic pressure, and do so by use of compressors.

I'm betting it's just combining Patricia and Patrick, both of which are abbreviated to the same thing, unlike for example Michael and Michelle.
