Choose the correct answer from the options given below:

(A) "We wanted to rent a flat near the university. ___, they were all too expensive."

• Needs a connector showing contrast/opposition between wanting to rent and the problem encountered.

(B) "I enjoyed reading the story. ___ it was very sad."

• Requires a connector showing contrast/concession - enjoying despite sadness.

(C) "These plants usually flower in spring. ___ won't, if there is frost."

• Needs a connector introducing an exception or contrasting condition.

(D) "We were working outside all day. ___, he was sitting inside watching television."

• Requires a connector showing simultaneous contrasting actions.

Option 1 → (A)-meanwhile, (B)-but, (C)-however, (D)-although → "Meanwhile" doesn't fit sentence A's contrast need. → Incorrect

Option 2 → (A)-meanwhile, (B)-although, (C)-however, (D)-meanwhile → "Meanwhile" in A is awkward; needs stronger contrast. → Less ideal but acceptable

Option 3 → (A)-meanwhile, (B)-but, (C)-although, (D)-however → "Meanwhile" doesn't work in A; "however" is weak for D's simultaneous action. → Incorrect

Option 4 → (A)-however, (B)-although, (C)-but, (D)-meanwhile → All connectors fit perfectly: "However" shows contrast in A, "although" shows concession in B, "but" introduces exception in C, "meanwhile" shows simultaneous action in D. → Most precise

Hence, Option 4 (and Option 2 as alternative) → Option 4 provides the most natural and grammatically precise connector choices, with "however" establishing clear contrast in sentence A and "meanwhile" perfectly indicating simultaneous actions in sentence D → correct
