In this question three statements are given followed by three conclusions I, II and III. You have to consider the three statements to be true even if they seem to be at variance from commonly known facts. Read all the conclusions and then decide whichof the given conclusion(s) logically follow(s) from the given statements.

The least possible Venn diagram is
Conclusions:
(I) Some metals can float. False (All metals are part of shiny and no shiny can float so it is false.)
(II) No brick can float. False (There is no direct relation given between them)
(III) Some bricks are shiny. True (All metals are part of shiny and some metals are bricks so it is true)
Hence, the correct answer is Only conclusion III follows.
