The textbook states this directly: "The earliest factories in England came up by the 1730s." Students often confuse this with the 1780s (when factories multiplied rapidly) or the 1810s (early 19th century growth). The key distinction is earliest factories (1730s) vs. rapid multiplication (late 18th century). Quote the textbook line if unsure — it earns the mark.
