About とされている

とされている is an expression that is commonly translated as 'to be considered as (A)', or 'to be regarded as (A)'. Conceptually, it is similar to にする, which means 'to decide on (A)'. However, due to する being in the passive form in this construction, it is closer to 'to be decided on', and expresses the general opinions/thoughts of large groups of people.

The と in this expression is a case marking particle, and expresses the result nuance of this particle.

Caution

The main difference between と as a case marking particle and と as a conjunction particle is that the case-marking particle will always link a single word/phrase to one specific word/result. The conjunction particle on the other hand, will often be followed by a 読点(とうてん) (Japanese comma), as it is separating two distinct thoughts within the sentence, rather than just a simple 'result'.

        This hint sounds strange. Maybe:

        • It is going off the assumption that (A) is true.
        • It assumes (A) is true.
        • (Or just remove that line – the hint works without it – “(A) is true” doesn’t trigger the memory of any grammar point.)

        私もそのためにここにきました！その点は文法点の説明に含みありません。その結果、思い出すとは手伝いません。私の日本語を是正してください！

        また、例の一つは「WP40」を口にする。しかし、「WP40」とは煙の手榴弾だって「WD40」とは石油に基づいた潤滑剤です！

        Summary

        I came here to mention this! It’s not mentioned in the details for the grammar point. As a result, it doesn’t help you remember.
        Also, one of the examples mentions WP40, but WP40 is a smoke grenade while WD40 is an oil-based lubricant!
