Place the following events in the order in which they occurred:


a.World War I occurs.
b.Australia and New Zealand become dominions.
c.Australia and New Zealand become independent countries.
d. Britain recognizes Australia and New Zealand as equals under the British Crown.

To place these events in chronological order, we need to determine the order in which the events occurred. Here are the steps to do so:

1. First, let's determine when World War I occurred. We can search for the start and end dates of World War I. It started in 1914 and ended in 1918.

2. Next, we need to establish when Australia and New Zealand became dominions. Dominion status refers to a self-governing entity within the British Empire. We can search for the year when Australia and New Zealand gained dominion status.

3. Then, we should find out when Australia and New Zealand became independent countries. This refers to the date when they gained full sovereignty and were no longer dependent on Britain.

4. Lastly, we have to confirm when Britain recognized Australia and New Zealand as equals under the British Crown. This recognition would have occurred after they became dominions or independent countries.

Using these steps, we can establish the correct order of the events:

1. World War I occurs (a) - 1914-1918.
2. Australia and New Zealand become dominions (b) - Typically for both countries, this occurred in the early 20th century, with Australia becoming a dominion in 1901 and New Zealand around the same time.
3. Australia and New Zealand become independent countries (c) - Australia became independent on January 1, 1901, through the Federation, while New Zealand gained full sovereignty and independence in 1947.
4. Britain recognizes Australia and New Zealand as equals under the British Crown (d) - This recognition happened after Australia and New Zealand became dominions and before they became fully independent countries. The exact year may vary, and researching the specific year of recognition would provide the most accurate answer.

Based on this information, the correct chronological order is:
(a) World War I occurs
(b) Australia and New Zealand become dominions
(d) Britain recognizes Australia and New Zealand as equals under the British Crown
(c) Australia and New Zealand become independent countries.
