premise: Batting proved awkward, however, with South Africa's all-seam attack able to extract plenty of bounce from the surface and India limped to lunch at 19 for two. Tea was taken early and extended by 44 minutes because of an approaching thunderstorm, with lightning flashing near the ground.
  Dravid was particularly watchful, eking out his runs in 151 minutes off 83 balls. Tendulkar was also cautious but his innings was interspersed with some sparkling strokes, including a cover drive off Ntini that raced to the boundary. He faced 89 balls and hit seven boundaries before edging an out-swinger from Kallis.
   What caused tea to be extended by 44 minutes?
hypothesis: South Africa's all-seam attack
