Expanation
1). No door is a room (E) à conversion à No room is door (E). Now, Some roofs are rooms (I) + No room is a door (E) = I + E = O = Some roofs are not doors.
Hence conclusion I follow
Again, Some windows are doors, (I) + No door is a rooms (E) = I + E = O = Some windows are not rooms.
Hence Conclusion II follows

2). There is no negative statements. Thus the positive possibilities can exist.
Hence both conclusion I and II follows.

3). Some cups are bottles (A) + All bottles are glasses (A) = A + A = A = All caps are glasses.
Hence conclusion II follows

4). No letter is a word (E) à conversion à No word is a letter (E). Now, Some vowels are words (I) + No word is a letter (E) = I + E = O = Some vowels are not letters.
Hence conclusion I follows.
Again, No vowels are words (I) = E + I = O* = Some words are not consonants.
Hence conclusion II does not follow.

5).  No vowel is a consonant (E) à conversion à No consonant is a vowel (E).
Hence conclusion I does not follow.
Again, Some words are vowels (I) + No vowel is a consonant (E) = I + E = O = Some words are not consonants.
Hence conclusion II follows.

6). No paper is a book (E) à conversion à No book is a paper (E). Now, All copies are books (A) + No book is a paper (E) = A + E = E = No copy is a paper (E) à implication à Some copies are not papers.
Hence I follows And Conclusion  II may follow from third statement.
Again, Some sets are papers (I) + No paper is a book (E) = I + E =O = Some sets are not books.
Hence III follows.

7). Some ropes are leashes (I) + No Leash is a rill (E) = I + E = O = Some ropes are not rills (O).
Hence conclusion I follows.
Again, All threads are ropes (A) à conversion à Some ropes are threads.
Hence conclusion II does not follow.
Now , No Leash is a rill (E) à implication à Some rills are not leashes (I).
Hence III follows

8). No cover is a box (E) à conversion à No box is a cover (E). Now, all tables are boxes (A) + No box is a cover (E) = A + E = E = No table is a cover (E).
Hence conclusion I does not follow.
Again, Conclusion II may follow from second statement.  All tables are tables (I) + No tables is a chair (E) = I + E = O = Some boxes are not chairs.
Hence III follows

9). First conclusion follows from first statement and second conclusion follows from third statement.
Thus, Conclusion I and II follows
Again, No dinar is a rupee (E) à conversion à No rupee is a dinar (E). Now, All coins are rupees (A) + No coin is a dinar (E) = A + E = E = No coin is a dinar.
Hence conclusion III does not follows

10). Conclusion I does not follow from third statement. Again, No cat is a dog à conversion à No dog is a cat (E).
Hence Conclusion II follows.
No Fox is a cat (E) + No cat is dog (E) = E + E = No conclusion.
But Conclusion III may follows


11). There is no negative statement. Thus the possibility in I exists. Hence conclusion I follows. All caps are pencils (A) à conversion à some pencils are caps (I).
Hence conclusion II follows.

12). No bag is a glass (E) + some glasses are not cups (O) = E+O =No conclusion. Hence conclusion I does not follow.
Again, No bag is a glass (E) à conversion à No glass is a bag (E). Hence conclusion II follows.

13). Some flowers are red (I)+No red is a tree (E) = I + E = O = Some flowers are not
trees. Hence conclusion I follows.
Again, No red is a tree(E) à conversion à No tree is red (E). Hence conclusion II follow as an implication of No tree is red.

14). All boxes are copies (A) + No copy is a book (E) =A + E = E = No box is a book. Hence conclusion I follows.
Again, All boxes are copies (A) à conversion à some copies are boxes (I). Hence conclusion II follows.

15). No cloth is a cover (E) + No cover is a wrap = E + E = No conclusion. Hence neither conclusion I nor II follows.

16). Some bowls are not jars (O*) + ( all spoons are jars (A) → conversion → ) Some jars are spoons (I) = O + I = No conclusion. Hence , conclusion I does not follow. But conclusion II follows.

17). All desserts are sweets (A) + No sweet is fruit (E) = A + E = E = no dessert is fruit (E). Hence conclusion I follows.
Again, No sweet is fruit (E) → conversion → No fruit is a sweet (E). Hence conclusion II follows.

18). No Circle is a wall (E) + All walls are homes (A) = E + A = O* = Some homes are not circles (O*). Hence neither conclusion I nor II follows. But both conclusions make a complementary pair (I-E). Hence either I or II follows.

19). No word is letter (E) + Some letters are vowels (I) = E + I = O* = Some vowels are not words (O*). Hence conclusion I does not follows. But the possibility in II exists.
Hence conclusion II follows.

20). Some informations are hopes (I) + Some hopes are sorrows (I) = I + I = No conclusion, but the possibility in II exists. Hence conclusion I does not follow. But II follows.
