Read the following early draft of an essay and then choose the best answer to the question or the best completion of the statement.

Passage:
(1) Have you ever worn a "lucky" pair of socks or engaged in a certain ritual before a performance?
(2) Recent research suggests that rituals do have benefits. (3) Even if they are really simple rituals. (4) After a loss, they can help people deal with grief, and before a high-pressure task, they can reduce anxiety and increase people's confidence. (5) Surprisingly, some research shows that rituals even benefit people who do not believe in them.
(6) In one recent experiment subjects received either a "lucky golf ball" or a regular one, and then had to perform a golf task. (7) In another experiment, subjects had to play a game: some of the subjects were told by a researcher "I'll cross my fingers for you," while the other half were not. (8) Similar experiments were conducted after subjects were told they lost a lottery, and the same results were seen. (9) Subjects who were put through a series of ritualistic tasks like making a drawing about how they felt, sprinkling salt on it, tearing up the paper, and counting up to ten reported feeling less disappointment afterwards than their counterparts who only drew how they felt. (10) Some rituals, admittedly, are stranger than others.
(11) Researchers are now looking further into which kinds of rituals are most effective. (12) For instance, do rituals involving more steps or more repetition work better? (13) We can continue to trust knocking on wood three times while wearing those lucky socks to help get us through our next big speech.
