Give the object number of the sample which has the relationship of "lying on" with object sample no.1 from image no.2345524.
object number of the sample refers to OBJ1_SAMPLE_ID; object sample no.1 from image no.2345524 refers to OBJ2_SAMPLE_ID = 1 and IMG_ID = 2345524
SELECT T2.OBJ1_SAMPLE_ID FROM PRED_CLASSES AS T1 INNER JOIN IMG_REL AS T2 ON T1.PRED_CLASS_ID = T2.PRED_CLASS_ID WHERE T2.IMG_ID = 2345524 AND T1.PRED_CLASS = 'lying on' AND T2.OBJ2_SAMPLE_ID = 1
