B: finding suitable examples Multiple choice
The question asks what both students are concerned about. They agree that they need to refer to specific cases, or suitable examples, and that this will take a lot of work.
“We've got to support our points by referring to specific cases. So that'll need a lot of work.”

The students decide to focus their assignment on housing for
A: family groups. Multiple choice
“Intergenerational living” paraphrases housing for family groups of different generations. They decide to focus on this rather than housing for elderly or single people.

B: constructing tall buildings. Multiple choice

use of roof space for gardens
B: This would be especially beneficial for city residents. Matching features
The students say roof gardens would improve the experience of living in an urban high-rise, especially without a balcony. This means the idea would be especially beneficial for city residents.

shared working spaces
E: This could encourage creativity. Matching features
They explain that people using shared working spaces can interact with others from different professions, which can generate new ideas and encourage creativity.
“That's often how new ideas get generated, by chatting to someone from a different profession.”

moveable internal walls
I: This would suit both existing and new members of a household. Matching features
Movable walls allow a home to adapt as household members’ needs change. The example includes both children who continue living with their parents and an elderly relative who moves in.
“It would mean they could still have their own space specially designed for their needs.”
- 27
smart mirrors in bathrooms
A: This could cause unnecessary anxiety. Matching features
The students think health-monitoring mirrors could make people worry unnecessarily about conditions that are not serious. This matches the idea of causing unnecessary anxiety.
“People might worry about conditions which aren't serious at all.”
- 28
bike sheds with charging points
D: This would have environmental benefits. Matching features
The charging points and secure bike storage could encourage people to cycle rather than drive. They say this would be better for the planet, so it would have environmental benefits.
“Yes, that would encourage more people to cycle instead of using their car. Much better for the planet.”
- 29
restriction of cars to certain areas
H: This would help some people but cause problems for others. Matching features
Keeping cars outside the development would create a pedestrian area, but the students point out that it could be difficult for disabled or elderly people. So it would help some people but cause problems for others.
“Maybe, but what if you're disabled or elderly and can't walk far? It wouldn't be so good for people like that.”
- 30
communal vegetable plots
G: This could enable retired people to share a project. Matching features
The communal vegetable plots would give older people an activity to share and help them get to know one another. This matches the idea of retired people sharing a project.
“That'd be a great way for older people to get to know one another, especially if they're no longer going out to work.”
