4. Textile industries allocate money for the purchase of sewing machines, fabrics and other products for example large circular knitting.

I chose this because it signifies that the textile industries are experiencing more demand on their product, meaning economic growth of the end consumer. By purchasing more sewing machins they are also stimulating the growth of the factories making them, which in turn grow the microchip industry and the needle industry etc. Thus expansion being seen all around.

Edit: The first statement in my opinion is misleading, as mass adoption of certain technology means that the old ones have already become obsolete. It also implies flooding the market and lowering prices thus, meaning that a peak has been reached and a drop is soon to occur due to oversupply.
