A factory is to commission two production lines. Production line 1 is to use existing technology. Production line 2 is to use the latest innovation in technology and, while promising to achieve considerable advances in productivity, it will take longer to start and is likely to experience teething problems. The graph indicates the production record of each line, in units of production (in 000s), over 9 months.

Production line 1 climbs at a fairly steady pace across the months (its path runs up through the region near points E and F). Production line 2 starts later at point A, rises to point B, then stays flat from point B to point C for a stretch of months, before climbing again through point D and point E to join production line 1 near point F.

Refer to the graph to answer the following:
A. Can the duration of reported breakdown be established?
B. Can the loss of production be quantified?
