use of ようから in this sentence


> 噂の広まりようから考えても、飛鳥の意見には同意せざるを得ない。

Even if (i) consider how the rumours spread , (I) can't help but agree with
Asuka's comments.

What is the function of ようから, and how does it differ from 噂の広まりようと考えても？

Thank you.




`masu-stem + よう` forms a noun phrase, "the way/manner of `verb`", "how
something `verb`".

噂の広まりよう **と** 考える is incorrect because "the quotative と" marks the content of
your thoughts itself. It's equally incorrect to the following sentence in
English:

> [×] I think, "The way rumors spread".

Note that "think something" and "think _about_ something" is different. In
this case, you need to say:

> I think _about_ how the rumors spread.

To say something like this, と is not an option. Instead, use the following
expressions:

> 噂の広まりよう **を** 考えても、…  
>  噂の広まりよう **について** 考えても、…

These would perfectly fit in your example sentence, too.

～ **から** 考える is less common, but it means something like "to think based on
～", "to think from ～'s perspective" or "to think with ～ as a starter",
depending on the context.
