1. The information in the graph_______________the statement that the number of international immigrants in France did not change significantly during the period from 1980 to 2005.
A. directly affirms
B. directly contradicts
 C. neither directly affirms nor directly contradicts

Explanation: the graph is the representing immigrants as a total percentage of population. Lets assume the population increased from 1980 to 2005, so the NUMBER of immigrants must also increase, but the graph which represents percentage of population may still stay the same.

2. During the interval________________the United States’ rate of growth in international immigrants as a percent of total population was less than that of at least one of the other countries included in the graph.

A. 1980–1995
B. 1980–2005
 C. 1995–2005

Ireland's growth rate is tremendous. It has doubled, from 7 to 14. Whereas the growth rate of US is not as much only 10.5 to 13.

1.The information in the graph_______________the statement that the number of international immigrants in France did not change significantly during the period from 1980 to 2005.

The %age increase/decrease in the number of international immigrants in France during the period from 1980 to 2005: 11, 10.9, 10.2,10.3,10.3,11,but
we don't know the population of France at the start of 1998, so we cannot actually infer that the population increased or decreased, could be could not be. 
So we have nothing to compare the increase/decrease in the above %ages.

Thus the information in the graph  neither directly affirms nor directly contradicts .
 Answer C.

2. During the interval________________the United States’ rate of growth in international immigrants as a percent of total population was less than that of at least one of the other countries included in the graph.

It can be easily inferred from the graph that for the period:
1980–1995 - US seems to higher growth as compared to other countries.
1980–2005 - US does have less growth for the given period, but its too long a period, US has higher growth in the middle years, in comparison to other countries.
1995–2005 -  In this particular period, we see that Ireland has a better and visible growth than US.

Answer C.

Question 1 : C 
1. The information in the graph_______________the statement that the number of international immigrants in France did not change significantly during the period from 1980 to 2005.

A. directly affirms
B. directly contradicts
 C. neither directly affirms nor directly contradicts

The graph represents the France % of total population, and that stays almost the same. But, we have to note here that the total population itself can go in either direction. Hence, we can't say anything about the number of international immigrants.

Question 2: C 
2. During the interval________________the United States’ rate of growth in international immigrants as a percent of total population was less than that of at least one of the other countries included in the graph.

A. 1980–1995
B. 1980–2005
 C. 1995–2005

In 1980-1985, US' rate of growth of population is from 6 to 7.2%. All other countries grow at a lesser % in these 5 yrs.
In 1985-1990, US' rate of growth of population is from 7.2 to 9%. All other countries grow at a lesser % in these 5 yrs. Ireland grows from 8-9% of total population.
 
 In the other years, Ireland surpasses this %. Hence C.

Can someone explain Q2? Why can't A be the answer? US is clearly below at least one of France and Sweden during those 15 years.

Sajjad1994 · Answer

Official Explanation

The scale on the graph's vertical axis represents the percentage of a country's population who are international immigrants. The line representing France is relatively flat, showing that the percentage of the people in France who were international immigrants did not change much from 1980 to 2005. But the graph does not indicate whether the number of people constituting France's total population changed significantly during that period. If France's population did change significantly, while the percentage of that population consisting of international immigrants remained about the same, then the graph would indicate that the number of international immigrants also changed significantly during that period. On the other hand, if France's population did not change significantly, then the graph would indicate that the number of international immigrants did not either. Thus, the graph neither directly affirms nor directly contradicts the statement that the number of international immigrants in France did not change significantly from 1980 to 2005.

The correct answer is neither directly affirms nor directly contradicts.

In the graph, the slope of the line representing any country represents that country's rate of growth in international immigrants as a percent of total population, with a steeper upward slope from left to right indicating faster growth. In both the section of the graph representing the period from 1980 to 1985 and the section representing the period from 1980 to 1995, the line representing the United States slopes upward from left to right more steeply than each of the other lines, indicating that the rate of growth in international immigrants as a percent of total population was greater in the United States than in each of the other nations during those periods. But in the section of the graph representing the period from 1995 to 2005, the line representing Ireland slopes upward from left to right more steeply than the line representing the United States does, indicating that the rate of growth in international immigrants as a percent of total population was greater in Ireland than in the United States during the interval from 1995 to 2005.

The correct answer is 1995–2005.

Hi, 
In Q2 why cannot the period from 1980 to 2005 be the answer? 
In 1980 to 2005 US grew by 7%, and Ireland by 8%. 
So US is below at least one other country?

Please advise where I am going wrong.

Sajjad1994 · Answer

The question is talking about the "rate of growth" and not the particular point of growth. So from the period of 1995-2000 Irelands rate of growth is more than the United states rate of growth. During the period 1980-2000, no other country has the greater rate of growth than the United State.

Hey  CEdward ,

I have the same question, I also chose the A  (1980-1985) .
The only reason I can think is that the question asks for the  rate of growth  so in this way implies the change of international immigrants as a percent of total population.

Could somebody help us?  Bunuel   KarishmaB   GMATNinja   GMATinsight   GMATCoachBen

GMATCoachBen · Answer

Gmatguy007 Yes, exactly! The key is understanding that "RATE of growth" means the SLOPE of the line (change in Y / change in X). A rate of growth normally has the time frame in the denominator. From 1995 to 2005, we see that the slope for the green line for the United States is lower (less steep) than the blue dashed line for Ireland: https://gmatclub.com/forum/download/file.php?id=81853 GMAT-Club-Forum-07i37pvv.png

Anonymous · Answer

Great, thank you GMATCoachBen ! Also, we can focus solely on the lines of USA and Ireland since both France and Sweden have relative constant rate of growth as we can see from the graph, right? Thank you in advance 😀 GMAT-Club-Forum-7pwsov70.png

GMATCoachBen · Answer

@Gmatguy007 We always focus on exactly what it's asking for! The question says: 2. During the interval _____ the United States’ rate of growth in international immigrants as a percent of total population was less than that of at least one of the other countries included in the graph. So, we are looking for a part of a line that is STEEPER than the United States' line, so our eye should immediately focus on the steepest part of one of the lines -- we see that it's Ireland from 1995 to 2005. There can only be one answer, so we can stop there. If we look at France and Sweden's lines, we can quickly see that they are not steeper than the United States' line. GMAT-Club-Forum-1tgubkrt.png

KarishmaB · Answer

The graph shows the percentage of international immigrants in each country's population over the years. For France this percentage has remained steady. 
For Ireland, there was some increase but very little from 1980 to 1995. From 1995 onwards, the percentage of international immigrants has increased rapidly in Ireland's population and is the maximum in 2005.
For US, the increase has been of about 1.5 percentage points per 5 years except recently when the increase is less. 
For Sweden, the increase has been of about 1 percentage point every 5 years.

The information in the graph ____ the statement that the  number  of international immigrants in France did not change significantly during the period from 1980 to 2005.

The graph shows us that percentage of international immigrants in France's population did not change significantly during the period from 1980 to 2005 but does it mean that the number of international immigrants did not change either? If France's population has increased in this period, then the number of international immigrants has also increased. If France's population has decraesed in this period, then number of international immigrants has also decreased. 
e.g. if France had 1000 people in 1980, it had 110 international immigrants.
In 2005, if FRance had 5000 people, then it had 550 international immigrants. But if it had 100 people in 2005, then it had 11 international immigrants.

ANSWER: Neither affirms nor contradicts

During the interval __________, the United States’ rate of growth in international immigrants as a percent of total population was less than that of at least one of the other countries included in the graph.

From 1980 to 1995, rate of growth in 'international immigrants as a percent of total population' in Ireland was very little. For US, the same was high.
From 1995 to 2005, the rate of growth in 'international immigrants as a percent of total population' in Ireland increased substantially (look at how high the slope of the IReland line is). For US the slope of the line is the same as before and lower than that of Ireland. Besides, IReland is starting from smaller population values so its rate would be much higher. If you are not sure, look at the calculation below to understand.

ANSWER: 1995 - 2005

Comparing rate of growth in 'international immigrants as a percent of total population' in various 5 year terms (not annual for simplicity)

1980 - 1985: Rate of growth in US = 1.5/6 * 100 = 25%; Rate of growth in Ireland = .5/6 * 100 = 8.3%

1985 - 1990: Rate of growth in US = 1.5/7 * 100 = 21.4%; Rate of growth in Ireland = 0%

1990 - 1995: Rate of growth in US = 1.5/8.5 * 100 = 17.6%; Rate of growth in Ireland = 0.7/6.5 * 100 = 10.7%

1995 - 2000: Rate of growth in US = 1.5/10 * 100 = 15%; Rate of growth in Ireland = 2.8/7.2 * 100 = 39%

2000 - 2005: Rate of growth in US = 1/11.5 = 8.7%; Rate of growth in Ireland = 4/10 * 100 = 40%

RenB · Answer

Hi, I am still unclear why 1980 to 2005 would be incorrect. If I draw 2 slopes for US and Ireland each, plotting the 1985 start point and 2005 end point, the Ireland slopw would still be greater than the US slope. Applying the same logic.  chetan2u   KarishmaB   Bunuel 
Someone mentioned in the post that 1980 to 2005 was not an option in the official explanation  Sajjad1994  can you please confirm

KarishmaB · Answer

Compare the growth rates in 1980 - 1995. The growth rate of US is higher than that of Ireland.

1980 - 1985: Rate of growth in US = 1.5/6 * 100 = 25%; Rate of growth in Ireland = .5/6 * 100 = 8.3%

1985 - 1990: Rate of growth in US = 1.5/7 * 100 = 21.4%; Rate of growth in Ireland = 0%

1990 - 1995: Rate of growth in US = 1.5/8.5 * 100 = 17.6%; Rate of growth in Ireland = 0.7/6.5 * 100 = 10.7%

The question wouldn't make sense (since we are given various possible time intervals to be filled in the blank) if the only thing relevant were the starting and the ending percentage figures. I would think you do need to be able to derive this understanding from the given graph and question.

chetan2u · Answer

RenB 
I would agree that there is no reason why 1980-2005 should not be a correct option.
As someone has mentioned, and also as can be seen in the explanation, the option should be 1980-1995 and not 1980-2005. I am making necessary changes.
