Economic growth patterns decreased sharply from 1990-1991. Then they rose sharply and gradually leveled off up until 1999. However, inflation dropped steadily from 1990-1999. It decreased sharply at first and then leveled off from 1994--1994.

Question 1 - Forecast of economic growth have consistently:

1- It over estimated economics growth from1990-1998
2- Underestimated economic growth from 1990-1998
3- Overestimated economic growth from 1996-1999
4- Underestimated economic growth from 1996-1999

Question -2 (Forecast of economists):
1. overestimated economic growth 199-1998.
2- underestimation inflation.
3- generally been accurate on inflation.
4- been less accurate than forecasts of economic growth.
5- been as accurate as those for economic growth.

2 and 1

Question 1 - Based on the given information, the correct answer is 2. Underestimated economic growth from 1990-1998.

Question 2 - Based on the given information, the correct answer is 3. Generally been accurate on inflation.

To answer these questions, we need to examine the provided information on economic growth patterns and inflation levels during the specified time period.

For Question 1 - Forecast of economic growth have consistently:

To determine whether the forecasts consistently overestimated or underestimated economic growth, we can compare the actual economic growth patterns with the forecasts during different periods.

From the given information, we know that economic growth decreased sharply from 1990-1991 and then rose sharply until 1999 before leveling off. To determine the accuracy of the forecasts, we can break down the time period into two parts: 1990-1996 and 1996-1999.

1. It overestimated economic growth from 1990-1998.
From the information provided, we cannot conclude whether the forecasts overestimated economic growth from 1990-1998.

2. Underestimated economic growth from 1990-1998.
From the information provided, we cannot conclude whether the forecasts underestimated economic growth from 1990-1998.

3. Overestimated economic growth from 1996-1999.
From the information provided, we cannot conclude whether the forecasts overestimated economic growth from 1996-1999.

4. Underestimated economic growth from 1996-1999.
From the information provided, we cannot conclude whether the forecasts underestimated economic growth from 1996-1999.

Based on the information provided, we do not have enough data to determine whether the forecasts consistently overestimated or underestimated economic growth.

For Question 2 (Forecast of economists):

To evaluate the accuracy of economists' forecasts on inflation, we need to analyze the given information.

From the provided information, we know that inflation dropped steadily from 1990-1999. It decreased sharply at first and then leveled off from 1994-1994 (which seems to be a typo, possibly meant to say 1994-1999). Let's evaluate the options provided:

1. Overestimated economic growth from 1990-1998.
Since this option refers to economic growth, it is not relevant to the question about inflation forecasting accuracy.

2. Underestimation inflation.
This option suggests that economists consistently underestimated inflation during the specified time period. However, according to the information provided, inflation steadily decreased from 1990-1999, which contradicts this option.

3. Generally been accurate on inflation.
Based on the information provided, it seems that economists were generally accurate in forecasting inflation, as it dropped steadily during the specified time period.

4. Been less accurate than forecasts of economic growth.
This option compares the accuracy of inflation forecasts to economic growth forecasts. From the information provided, we cannot determine whether inflation forecasts were less accurate than economic growth forecasts.

5. Been as accurate as those for economic growth.
This option suggests that inflation forecasts were equally accurate as economic growth forecasts. Based on the information provided, we cannot determine whether this option is accurate or not.

To summarize, from the given information, it seems that economists were generally accurate in forecasting inflation as it steadily decreased from 1990-1999. However, we cannot determine the accuracy of inflation forecasts compared to economic growth forecasts or the specific overestimation or underestimation of economic growth forecasts.
