NEW YORK (TheStreet) -- Jim Cramer answers viewers' Twitter (TWTR) questions from the floor of the New York Stock Exchange.

Cramer said he wasn't surprised by the correction in the Chinese stock market. "China was this giant bubble because they added about 20 million retail [brokerage trading] accounts. As soon as they got the money, put it into an account they bought stocks. Didn't matter what they bought," said Cramer. "They levered up, this is what happens. It was ridiculous what the Chinese did -- they should never have allowed all these retail accounts. It's almost as if they don't care," he added.

Cramer answered a question about Hertz (HTZ) stock: "Accounting irregularities means sell."

One viewer asked about Magellan Midstream Partners (MMP), which Cramer said is a good company. But as interest rates go higher, the stock will go lower, he predicted. Within the energy space, Cramer also likes Energy Transfer Partners (ETP) and Kinder Morgan (KMI). 

Is Kraft (KRFT) a buy if its deal with Heinz goes through? Cramer said, "Absolutely yes. Kraft is going to be a winner. They'll be able to make acquisitions. It's a terrific situation." Heinz (HNZ) and Kraft agreed to merger in March, and Kraft shareholders are set to vote on the deal next week.

Cramer was asked if the new Trans-Pacific Partnership will help Nike (NKE) move to new highs. He said Nike stock is a buy because its direct-to-consumer business is great and the company is hitting on all cylinders.

Another viewer asked about whether to sell a position in Keurig Green Mountain (GMCR). Cramer commented, "They had a horrible quarter, maybe the worst of any company during the year." He added that at a certain point, Coca-Cola (KO) might buy the company out. He suggested owning Monster Beverage (MNST), placing a $162 price target on the stock.
