To solve this problem, we need to find the two closest numbers from a given list of floats and return them in ascending order. The key insight is that the closest numbers in a sorted list will be adjacent. By leveraging this property, we can efficiently determine the closest pair by examining consecutive elements in the sorted list.

### Approach
1. **Sort the List**: First, we sort the input list. Sorting ensures that the closest numbers will be adjacent, simplifying the search process.
2. **Iterate Through Consecutive Pairs**: We then iterate through each consecutive pair of elements in the sorted list.
3. **Track Minimum Difference**: For each pair, we compute the difference and keep track of the smallest difference encountered. The pair with the smallest difference is our result.

### Solution Code
```python
from typing import List, Tuple

def find_closest_elements(numbers: List[float]) -> Tuple[float, float]:
sorted_numbers = sorted(numbers)
min_diff = float('inf')
closest_pair = (sorted_numbers[0], sorted_numbers[1]) # Ensured by problem constraints

for i in range(len(sorted_numbers) - 1):
a, b = sorted_numbers[i], sorted_numbers[i+1]
current_diff = b - a
if current_diff < min_diff:
min_diff = current_diff
closest_pair = (a, b)

return closest_pair
```

### Explanation
1. **Sorting**: The list is sorted to ensure that any two closest numbers are adjacent. This reduces the problem complexity from checking all possible pairs to just consecutive pairs.
2. **Finding Minimum Difference**: By iterating through the sorted list and comparing each consecutive pair, we efficiently find the smallest difference. The first occurrence of the smallest difference is tracked, ensuring the correct result is returned even if multiple pairs have the same difference.
3. **Return Result**: The closest pair found during the iteration is returned in ascending order, which is naturally maintained due to the sorted list.

This approach ensures an optimal solution with a time complexity of O(n log n) due to sorting, followed by a linear scan O(n) to find the closest pair. This is efficient and handles all edge cases, including duplicates and multiple pairs with the same minimum difference.		 passed

Qwen2-72B-Instruct Here is the python function that completes the given code:

```python
from typing import List, Tuple

def find_closest_elements(numbers: List[float]) -> Tuple[float, float]:
numbers.sort()

if numbers[i] - numbers[i-1] < min_diff:
min_diff = numbers[i] - numbers[i-1]
result = (numbers[i-1], numbers[i])
return result
```
However, this function has a complexity of O(n log n) because of the sort operation. If you want a more efficient solution with O(n) complexity, you can use this:

```python
from typing import List, Tuple

def find_closest_elements(numbers: List[float]) -> Tuple[float, float]:
numbers.sort()
min_pair = (numbers[0], numbers[1])
min_diff = abs(numbers[1] - numbers[0])

diff = abs(numbers[i] - numbers[i-1])
if diff < min_diff:
min_diff = diff
min_pair = (numbers[i-1], numbers[i])
return min_pair
```
But remember, this more efficient solution requires that the input list is not empty.

In the second solution, the numbers are first sorted and then the minimum difference between consecutive elements is found, which is then returned. This solution assumes that the smallest difference will be between two numbers that are close in the sorted list.		 passed
baichuan4 To complete the Python code for finding the two closest elements in a list, you can use the following approach:

This code first sorts the input list of numbers in ascending order using the `sorted` function. Then, it initializes the `closest_pair` variable with the first two numbers from the sorted list and calculates their absolute difference as the initial minimum difference.

Next, it iterates through the sorted list from the second element to the second-to-last element (index 1 to `len(sorted_numbers) - 2`). For each pair of adjacent numbers, it calculates their absolute difference and checks if it is smaller than the current minimum difference. If it is, the `closest_pair` and `min_difference` are updated.
