19. The second paragraph contrasts -

(1) sand dunes in Africa and Asia with dunes in North America
(2) booming beaches with booming sand dunes
(3) squeaking sand with whistling sand
(4) squeaking sand with booming sand

20. According to the last paragraph, early research on booming sand is unreliable because -

(1) in the past, it was impossible to reproduce in laboratories the sounds made by
different types of sand

(2) booming sand and squeaking sand were studied as though they were the same
phenomenon

(3) researchers had never actually heard booming sand
(4) researchers did not recognize the rarity of the phenomenon

21. It can be inferred that the questions asked in the last paragraph -

(1) have not yet been fully answered
(2) are impossible to answer
(3) have many different answers
(4) were answered by early researchers

22. An appropriate title for the text would be -

(1) The Sounds that Sand Makes: Squeaking, Whistling and Booming
(2) Recent Research on a Rare Desert Phenomenon
(3) The Mystery of Booming Sand: From Marco Polo to Modern Times
(4) The Sand Dunes of Africa, Asia and North America
