The table below shows how to choose an appropriate glue for different materials you may want to bond together. For example, to bond cork and rubber you can use either rubber contact glue or epoxy glue.
Determine what they are trying to ask, and what you will need to solve it
Eliminate any non-essential information
Draw a picture, graph, or equation
In moments of high stress like exam taking, always work with the paper they give you to avoid careless mistakes.
Solve.
This question is pretty straightforward, it is just testing your ability to sort through a lot of information and using tables with keys. To solve, just take each statement in the answer and try to disprove it.
A Acrylic can be bonded to polystyrene using cyanoacrylate.
Look at the top and find acrylic, then pair it with polystyrene on the left side index. You will see that they can be bonded together using PVA glue (D) or latex glue (H). Therefore A is incorrect.
B Synthetic resin glue can only be used to glue wood materials together.
Synthetic resin glue is E in the key. E can be found only in the boxes glueing plywood to plywood, or plywood to balsa wood. Therefore B must be correct as this glue can only be found glueing these wood materials together.
C Balsa cement can only be used to glue balsa wood to another material.
Balsa cement has a code C, which can be found glueing balsa wood to card and itself, but also can be found glueing card to different materials. Therefore C is incorrect.
D The only materials that are suitable for bonding together with three different types of glue are cork with cork.
This is an easy one to spot, acrylic and card also have three different types of glue that can hold them together (PVA glue, superglue, epoxy glue). Therefore D is incorrect.
E Polystyrene and card can only be bonded with rubber contact glue.
The code from the key that glues polystyrene and card together is D, for PVA glue. Therefore E is incorrect.
