### Question
How many objects can you spot in image no. 72? What objects may be identified on the same image and within the bounding box represented as (341, 27, 42, 51)?

### Hint
How many objects refers to OBJ_CLASS_ID; image no. 72 refers to IMG_ID = 72; What objects refers to OBJ_CLASS; bounding box represented as (341, 27, 42, 51) refers to X = 341 and Y = 27 and W = 42 and H = 51

### SQL
SELECT SUM(IIF(T1.IMG_ID = 1, 1, 0)), SUM(IIF(T1.X = 341 AND T1.Y = 27 AND T1.W = 42 AND T1.H = 51, 1, 0)) FROM IMG_OBJ AS T1 INNER JOIN OBJ_CLASSES AS T2 ON T1.OBJ_CLASS_ID = T2.OBJ_CLASS_ID

### Question
On image no. 5, name the attributes that are composed of multiple objects.

### Hint
image no. 5 refers to IMG_ID = 5; name the attributes refers to ATT_CLASS; multiple objects refers to count(ATT_CLASS) > = 2

### SQL
SELECT T2.ATT_CLASS FROM IMG_OBJ_ATT AS T1 INNER JOIN ATT_CLASSES AS T2 ON T1.ATT_CLASS_ID = T2.ATT_CLASS_ID WHERE T1.IMG_ID = 5 GROUP BY T2.ATT_CLASS HAVING COUNT(T2.ATT_CLASS) > 2
