3.1. Match the headings with the texts. There are two extra headings that you do not need to use. Headings: 1. The man behind the mask; 2. A variety of functions; 3. Pay to throw away; 4. Free some space; 5. A lucky superhero; 6. Manual labour. Texts A–E.

A — 6. Manual labour.

B — 6. Manual labour.

C — 2. A variety of functions.

D — 4. Free some space.

E — 1. The man behind the mask.

Text A describes children learning to do chores, and B explains how washing clothes used to require manual work. C is about a robot performing different cooking tasks, D is about clearing clutter, and E introduces the person behind the superhero name.

Note: The visible text suggests that heading 6 could apply to both A and B, so the headings cannot be matched one-to-one with certainty from the provided page. Headings 3 and 5 do not clearly match the visible texts.
