In the following question, two separate sentences with a few highlighted words have been given. Answer the questions, based on the given sentences.

The highlighted words in the given sentences may or may not have been used in the correct sequence. You are required to choose the correct sequence of words to form meaningful sentences.

(A) The first wave of the pandemic attempts (A) the world revealed (B) the vulnerabilities in the global (C) healthcare system.

(B) Hospitals have been replenish (D) for nearly a year, and no throughout (E) have been made to swamped (F) medical oxygen supplies.

The correct option/sequence is EBCFAD.

Let's analyze the given sentences and find the correct arrangement of the highlighted words to make both sentences grammatically correct and contextually meaningful.

We are given two sentences with six highlighted words:
Sentence (A): The first wave of the pandemic attempts (A) the world revealed (B) the vulnerabilities in the global (C) healthcare system.
Sentence (B): Hospitals have been replenish (D) for nearly a year, and no throughout (E) have been made to swamped (F) medical oxygen supplies.

Let's look at the grammar and meaning of Sentence (A):
- "The first wave of the pandemic [word] the world..."
We need a preposition or a participle here to connect the pandemic to the world. Looking at the options, throughout (E) fits perfectly to indicate the duration or spatial spread: "The first wave of the pandemic throughout (E) the world...".
- "...[word] the vulnerabilities in the [word] healthcare system."
The subject is "The first wave of the pandemic throughout the world". The main verb of the sentence should describe what this wave did. The word revealed (B) fits naturally as the verb: "...revealed (B) the vulnerabilities...".
- The adjective global (C) correctly describes the healthcare system: "...in the global (C) healthcare system."
So, Sentence (A) becomes: "The first wave of the pandemic throughout (E) the world revealed (B) the vulnerabilities in the global (C) healthcare system."
This gives us the sequence for the first three positions as E, B, C.

Now let's look at Sentence (B):
- "Hospitals have been [word] for nearly a year..."
"have been [past participle]" is needed for passive voice. The word swamped (F) fits perfectly here to indicate that hospitals have been overwhelmed: "Hospitals have been swamped (F) for nearly a year...".
- "...and no [word] have been made to..."
"no [plural noun]" is required to agree with "have been made". The word attempts (A) is a plural noun that fits contextually: "...and no attempts (A) have been made...".
- "...to [word] medical oxygen supplies."
"to [infinitive verb]" is required. The verb replenish (D) fits perfectly here: "...to replenish (D) medical oxygen supplies."
So, Sentence (B) becomes: "Hospitals have been swamped (F) for nearly a year, and no attempts (A) have been made to replenish (D) medical oxygen supplies."
This gives us the sequence for the remaining three positions as F, A, D.

Combining the positions in order, we get:
1st position: E
2nd position: B
3rd position: C
4th position: F
5th position: A
6th position: D
Thus, the correct sequence is EBCFAD.
