Q:

What kind of adverb is ‘’jedoch’’

Hello everyone i’m learning about adverbs, they are separated in 4 class(lokal, temporal, modal and kausal) but i couldnt’t find and understand in which class ‘’jedoch’’ belongs 
This sentence for example 
‘’Du kannst mit ihnen jedoch auch die Folgen von etwas beschreiben.’’ 
i ask the verb questions: wie, warum, weshalb... but i can’t understand

A:

Jedoch, as an adverb, is a Modaladverb because it indicates the extension of an action.  Some examples:

Die Sonne schien, es war jedoch kalt. 

Es war kalt, wir froren jedoch nicht. 

In the first sentence, the sun shines less intensely than necessary to make it warm.  In the second example, it wasn't as cold to make them freeze.  As you can see here, jedoch usually restricts the extent of an action. 
The construction jedoch auch from your example, however, is mostly used to restrict the extent of the precedent action, hence allowing for the action in the current sentence to take place:

Die Sonne schien, es regnete jedoch auch. 

Here, jedoch auch indicates that the shining sun wasn't the only weather condition at that time.  It restricts the absoluteness of the preceding action so to speak. 
Thus, in

Du kannst mit ihnen jedoch auch die Folgen von etwas beschreiben. 

jedoch auch means that you can do more with 'them' (ihnen) than was said before.
