Page 155, set 4, page 155, in the first first table: The symbol should be a dollar not a euro sign.

Page 168, set 11, question 2, Table for House Price Index: The percentages for New Zealand should be negative.

Page 169, set 13, question 2: Option "A" appears 5 times instead of A, B, C, D, E.

Page 170, set 15: The header for the second table should say: Gross disposable income of households (million euros)

Page 185, set 33: Correction: Sapin → Spain

Page 189, set 39: It's hard to distinguish the categories in the diagram due to the colours. Maybe use various types of shading for some categories? Resolution: I agree, it is a bit of a challenge – we will adjust the design.

Page 218, set 18, Q3, right-hand column, line 6 (cf. table on page 173): Correction: 348 460 → 348 450

Page 175/221, Q3: Answer incorrect.
Reasoning: 1 600 / 189 ≈ 8.88, not ≈ 8.87. This changes the distance covered from 1 182 m to 1 184 m and hence the distance between the runners in question from 18 m to 16 m, which means option C (15.1 m) rather than option D (17 m) is correct.
Yes, indeed, well spotted!
Rounding 1 600 / 189 ≈ 8.89 and replacing 8.87 in the calculation with 8.89 makes the calculation 1 200 - 1 185 = 15, so Option C is the correct answer, not Option D.

Page 226, set 24, question 2: Change the word ‘protein’ to ‘fat’ (also in the explanation) : How much more fat content was produced in 2022 in Finland due to a higher fat content percentage as compared to the fat content that would have been produced in 2022 had the fat content percentage stayed at the level of 2018 (in tonnes).

Page 239, set 33, question 3: The correct answer is B, not C, and the calculation should say “option B is closest in value”.

Page 249, set 40, Q3, left-hand column, line two up from the bottom: Correction: 2019 → 2021

Page 280, question 19: the 5th image should contain a 6-sided black polygon (because 10 quadrilaterals - 4 triangles = 6), and the sentences: "nine rectangles, four triangles and a black pentagon in the corner" has to be changed to "ten rectangles, four triangles and a black hexagon in the corner"; "We will verify the fifth figure now. 9 rectangles minus 4 triangles = a five-sided black shape (i.e., a pentagon)" has to be changed to "We will verify the fifth figure now. 10 rectangles minus 4 triangles = a six-sided black shape (i.e., a hexagon)

Page 285, question 24, right column: "In option C, both the colour..." should read " In option D...." (Note: this question is not in the November 2024 print edition/ebook)

Page 306, set 40, Q45: Since option B had already been eliminated at the bottom of the left-hand column, the following sentence:
"We now have to decide between A and B."
should presumably be:
"We now have to decide between A and D."
Correction applied.

Additional points for review

Page 38, eight/seven lines up from the bottom: Correction:
“…: it could just as well wave been given …”
→ “…: it could just as well have been given …”

Page 142, under "Calculation": Correction:
"Hence" and "Portugal's new GDP is:" probably need to go after the first equation (Tax to GDP Ratio = Tax Revenue / GDP), and the calculation itself (87.2445 / 0.4697 ≈ 185.745) probably needs to go after the second equation (GDP = Tax Revenue / Tax to GDP Ratio).
Resolution: Agree, that would read more logically.

Right-hand column:
Correction:
"How many more (or less) Swiss francs …"
→ "How many more (or fewer) Swiss francs …"

SET 40, Q1. Correct Answer: E

Reasoning

We need to calculate the total amount of fat consumed and then calculate the daily consumption.

Calculation

We need to work out the total amount of fat consumed, which is the amount per person (both saturated and unsaturated), multiplied by the number of people. This gives: (2.44 + 2.19) × 60120 = 278356 This is now in kg/year and we want the daily rate, so we divide by 365 days/year: 278356 / 365 = 762.6 kg/day

You must be careful at this point not to think you have finished the question and mark option B as the correct answer, because you still have to correct the order of magnitude. The population is in thousands so we need to multiply by 1000, giving us 762600 kg per day. The answer options expressed in kg are much lower figures than this, but if we divide by 1000, to convert kg to tonnes, we get 762.6 tonnes, which is option E.

– Question 13 (page 49): instead of options, it directly gives the answers.

A. The bridge above a valley in the Shiniuzhai National Geological Park was entirely rebuilt to make it safer than the original wooden bridge.
B. The Shiniuzhai National Geological Park’s bridge and the bridge in the Zhangjiajie Grand Canyon area are designed by architect Haim Dotan.
C. China is the only country to build features like these dizzying structures.
D. The bridge above a valley in the Shiniuzhai National Geological Park is 300 metres long and made of glass panes that are 24mm thick.
