Answer:
A. die Wäsche waschen
Explanation:
B means<em> do the dishes</em>; C is <em>clean the kitchen</em>, and D is <em>mow the lawn. </em>These phrases do not work in the sentence in question, which is about doing the laundry.
The middle is the nucleus.
Answer:
(1) Kennen
(2) Wissen
(3) Kennen
(4) Wisst
(5) gewusst
(6) Kennen; kennt
(7) Weißt
Explanation:
The difference between <em>kennen</em> and <em>wissen</em> is tricky for English-L1 learners because they can both translate to the same "to know." (Interestingly, for native German speakers, they are semantically clearly delineated and there is absolute no confusion about when to use which.)
There are many websites listing hints on when to use which, but I find the following most useful:
Kennen: if you can replace it with "recognize" then it is likely a candidate for "kennen." For example, the first sentence in your problem "Do you know the saying?" --> "Do you <em>recognize</em> the saying?" (hence, use "kennen")
Wissen: you have "knowledge about something" For example, in the first sentence of your problem, if you plug in "Do you have knowledge about the saying" - that sounds clumsy, so "wissen" is not a good candidate (in contrast to the "recognize/kennen" test). But for sentence #2: "(do you have knowledge about) how many people live in Germany" - that sounds like a good fit, and "wissen" is appropriate.
Eventually, with practice you will be able to distinguish the two appropriately and quickly.
The Germans treated the jews badly because Hitler thought that anyone who did not have blond hair or even blue eyes were on the lowest ranking on the social ranking and should be treated like trash. So Hitler somehow got millions of people to believe that the jews betrayed them and should be wiped off the face of the earth, in the process, they went after Gypsies, Jehova's Witness, handicapped, and homosexuals.
