Award [1] for working/calculation and [1] for correct answer.
Working/calculation [1]

500 − 19 = 481, then 481 500  × 100 ;

(500 − 19)/500 × 100;
500 -- 100 % then 19 ---- 3.8 % followed by 100 - 3.8;
500 -- 100% then 19 ---- 3.8 % followed by 481 ---- 96.2 %;
500 −19 = 481 then 500 -- 100% followed by 481 ---- 96.2 %;
19/500 = 0.038 then 1− 0.038 = 0.962.

Answer [1]
= 96 / 96.2

 

a.

This question requires “Resource Booklet - Nov 2018 SL paper 1”, available under the "your tests" tab > supplemental materials.

less demand for beaver pelts/fur / people no longer want to wear fur / change in fashion tastes / fur no longer considered beautiful;
changing attitudes towards hunting;
alternative materials available, eg synthetics developed;
glut in market (oversupply) from other areas reducing unit price / large number of beavers in 2015 resulted in cheaper pelts.

Do not accept “almost extinct in 1900” since the two comparative dates are 1940 and 2015.
Do not accept “beavers are considered by IUCN as least concern”.
Do not accept only “there has been an increase in numbers”.

Examiners report

The majority of students correctly conducted this calculation and achieved full marks. A few candidates lost a mark by not showing any workings of the calculation.

a.

There were mixed responses to this question. A common error was not linking the high number of beaver pelts in 2005 to lower prices compared to 1940. Many candidates just referred to beavers nearly becoming extinct in 1900 or its IUCN status.
