11i10Because the x-axis shows the time that packets appeared12br
10on a link within the network, the sequence of events at the12br
10sender has to be inferred from the graph. After the first Fast12br
10Retransmit, when the sender's congestion control window12br
10reaches four, the sender transmits packets 29-32. The sender12br
10receives an ACK for packet 29, and transmits packets 33 and12br
1034. Next the sender receives an ACK for packet 30, and12br
10retransmits packets 35 and 36. Finally, the sender receives12br
10two dup acks for packets 42 (as responses to packets 31 and12br
1032). At this point the congestion window is 6, and the sender12br
10transmits packets 43-48.12i12br

10She was discussing about an observation which was plotted on a graph (not shown). At first, she used simple past (in the first paragraph), and then in the second paragraph, she started to elaborate in simple present. Is this correct and why? I am confused now. 12br
