## **Core Concept**
The Millennium Development Goals (MDGs) were established by the United Nations to address various global health and development issues. One of these goals focused on improving maternal health, specifically targeting the reduction of Maternal Mortality Ratio (MMR). The MDGs were a set of eight international development goals for the year 2015 that had been established following the Millennium Summit of the United Nations in 2000.

## **Why the Correct Answer is Right**
The correct answer, **three-quarters**, refers to the specific target set under the Millennium Development Goals, particularly MDG 5, which aimed at improving maternal health. The goal was to reduce by three-quarters, between 1990 and 2015, the maternal mortality ratio. This target was a significant global effort to decrease the number of maternal deaths and improve healthcare for women during pregnancy, childbirth, and the postpartum period.

## **Why Each Wrong Option is Incorrect**
- **Option A:** This option is incorrect because it does not specify the correct proportion or timeframe related to the MDGs' target for reducing MMR.
- **Option B:** This option is incorrect as it also does not accurately reflect the target set by the MDGs for the reduction of MMR.
- **Option D:** This option is incorrect because it suggests a different proportion than the one specified by the MDGs for reducing MMR.

## **Clinical Pearl / High-Yield Fact**
A significant clinical pearl from the MDGs is the emphasis on maternal health as a critical component of global health initiatives. The focus on reducing MMR by three-quarters between 1990 and 2015 highlighted the need for improved prenatal, delivery, and postnatal care. This goal has carried forward into the Sustainable Development Goals (SDGs), with a renewed focus on ending preventable maternal mortality.

## **Correct Answer:** . **three-quarters**
