Teacher: In this task, you're given a short article. Your job is to classify the article based on its category. Use the following classification labels, 0. World, 1. Sports, 2. Business, 3. Science or Technical. Label the text "0" if it contains information related to world. Label the text "1" if it contains information related to sports. Label the text "2" if it contains information related business. Label the text "3" if it contains science or technical related information. 
Teacher: Now, understand the problem? If you are still confused, see the following example:
The Race is On: Second Private Team Sets Launch Date for Human Spaceflight (SPACE.com) SPACE.com - TORONTO, Canada -- A second team of rocketeers competing for the  #36;10 million Ansari X Prize, a contest for privately funded suborbital space flight, has officially announced the first launch date for its manned rocket.
Solution: 3
Reason: This statement indicates that it is related to space which is in fact related to science. This is a positive example because the label correctly classifies the statement as science. 

Now, solve this instance: SanDisk flashes new memory cards SanDisk this week announced a series of CF (CompactFlash) cards that double the read and write speeds of its fastest flash cards available today, as well as an 8GB version of its Ultra II CF Type 1 flash memory card.
Student:

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.
