I- type statements can't be combined. However, II and II from a complementary I-E pair. So do III and IV Hence either I or II and either III or IV follows.

All tables are boxes + All boxes are trunks = A + A = A = All tables are ? trunks ? conversion Some trunks are tables (I) Hence I follows. All chairs are tables + All tables are boxes = A + A = A = All chairs are boxes Hence II follows. All desks are chairs + All chairs are boxes = A + A = A = All desks are boxes ? conversion ? some boxes are desks (I) Hence III follows. All desks are boxes + All boxes are trunks = A + A = A = All desks are trunks Hence IV follows.

All flowers are jungles + All jungles are tubes = A + A = A = All flowers are tubes ? conversion ? Some tubes are flowers (I) Hence Iv follows. Some rains are flowers + All flowers are tubes = I + A = I = Some rains are tubes ? conversion ? Some tubes are rains (I) Hence II follows. Some rains are flowers + All flowers are jungles = I + A = I = Some rains are jungles ? conversion ? Some jungles are rains (I) Hence III follows. Some tyres are rains + Some rains are jungles = A + I = No conclusion Hence I does not follow.

Some rollers are wheels + All wheels are mats = I + A = I = Some rollers are mats ? conversion ? Some mats are rollers (I) Hence I follows. Some rollers are mats + Some mats are cars = I + I = No conclusion Hence III does not follow. All belts are rollers (A) ? conversion ? Some rollers are belts(I) Hence IV follows. All belts are rollers + Some rollers are mats = I + A = No conclusion Hence II does not follow.

I-type statements can't be combined.

Some cables are brushes + All brushes are paints ? conversion ? Some paints are cables (I) Hence I follows. All bulbs are wires (A) ? conversion ? Some wires are bulbs (I) Hence II follows. No wire is cable + Some cables are brushes = I + E = O* = Some brushers are not wires Hence III does not follow. All bulbs is cable ? conversion ? No cable is bulb (E) Hence IV does not follow.

All keys are balloons + Some balloons are mirrors = A + I = No conclusion Hence I does not follow. All chairs are keys + All keys are balloons = A + A = A = All chairs are balloons ? conversion ? Some balloons are chairs (I) Hence II follows. Some balloons are mirrors (I) ? conversion ? Some mirrors are balloons (I) Hence III follows.

Some drums are posters + All posters are windows = I + A = I = Some drums are windows ? conversion ? Some windows are drums (I) Hence I follows. All posters are windows + Some windows are tablets = A + I = No conclusion Hence neither I or III follows.

All branches are nets + Some nets are dresses = A + I = No conclusion Hence I and IV does not follow. Some trains are branches ? conversion ? Some branches are trains (I) Hence III follows. Some trains are branches + All branches are nets = I + A = I = Some trains are nets ? conversion ? Some nets are trains (I) Hence II follows.

Some kites are desks + All desks are jungles. = I + A = I = Some kites are jungles ? Conversion ? Some jungles are kites (I) Hence IV follows. some pencils are kites + Some jungles are kites = I + I = No conclusion Hence I and II does not follow. All desks are jungles + All jungles are mountains = A + A = A = All desks are mountains ? Conversion ? Some mountains are desks (I). Hence III follows.
