What does "among other donors" in the last sentence mean? Does it mean "there are other donors which also make great increases" or "among the donors except the three largest donors"?

The three largest donors continue to be the US, Germany and the
UK. These countries accounted for 52% of all government contributions, although
contributions from all three decreased in 2018. Among other donors, substantial
increases were made by the United Arab Emirates and Saudi Arabia, providing an
additional US$1.7 billion (567% rise) and US$806 million (173% rise) in 2018, respectively.

Read sentence 13 from the draft. some plants retain a great deal of their foliage through much of the spring and summer, but the leaves do not retain their green color for long. which detail would be best to add after sentence 13 to develop the topic? a. since the green color of the leaves that are bright and abundant during the warmer months will disappear by the time it is fall, it is important that the leaves are trimmed and kept freshly cut so that they will last for as long as possible. b. while the temperature outside may dictate when the fall colors of leaves appear, it is only one of many environmental factors that play a part in the changing of colors from green leaves to fall-colored leaves during the cooler months. c. if people want to enjoy the green color of leaves longer, trees should be planted where the environment is warmer and the days longer because chlorophyll in the leaves can only be manufactured and replaced with sunlight and warmth. d. the green chlorophyll normally masks the fall-colored pigments during the warmer months, but as sunlight becomes less abundant and trees become frozen, the fall colors of leaves become more visible as chlorophyll disappears.
