Answer 3

As an AI language model, I don't have the ability to read books or perceive time in the same way humans do. My knowledge is based on the information available up until September 2021. I don't have the capability to continuously read or experience new things beyond that date.

As for your second question, it seems like you're asking how to conjugate the verb "to read" in the present perfect tense in Russian. Here's the correct form:

Как долго ты читаешь эту книгу? (Kak dolgo ty chitayesh etu knigu?) This translates to "How long have you been reading this book?"

In this case, the verb "читать" (chitat') meaning "to read" is conjugated in the present perfect tense. The construction "ты читаешь" (ty chitayesh) is the present tense form of "you read," and when combined with the auxiliary verb "как долго" (kak dolgo) meaning "how long," it forms the present perfect tense to inquire about an action that started in the past and is still relevant in the present.
