Thus, when car A is 3 blocks north of the intersection and car B is 4 blocks east of the intersection, the distance between them is decreasing at a rate of 2 mph. The topic model identified three topics: (1) requests for support measures for distance learning, (2) concerns about distance learning and its application, and (3) anxiety about the government decrees introducing red zones and corresponding restrictions. On the other hand, the fraction of tweets on topic 1 (digital support) decreased during the second period and then grew slightly in the last period.
