I want to know the answer to the following question:
What problem continued to stop rescue teams from reaching affected areas?
All the background I'm provided with is that "The Red Cross Society of China also stated that the disaster areas need tents, medical supplies, drinking water and food; however it recommended donating cash instead of other items, as it had not been possible to reach roads that were completely damaged or places that were blocked off by landslides.". Is that enough to answer the question?
Answer: yes
