6. Consider the linear population model with intercept:$y_t = \alpha + \beta x_t + \varepsilon_t$The variance structure is known as below: $E(\varepsilon_t^2) = \sigma^2 h_t^2,$Which regression may obtain efficiency $\hat{\beta}$ estimator? (A) Regress \( y_{t} \) on 1, \( x_{t} \) (B) Regress \( y_{t} / h_{t} \) on 1/ht ,xt/ht(C) Regress \( y_{t} / h_{t}^{2} \) on 1/h2t ,xt/h2t(D) Regress \( y_{t} \) on 1/ht ,xt/ht(E) Regress \( y_{t} / h_{t} \) on 1, \( x_{t} \)

5. Consider the linear model with intercept: $y_t = \alpha + \beta x_t + u_t$ If the $A = \sum_{i=1}^{n} (x_i - \bar{x})^2$ is positive definite and $E(u_i \mid x_i) = 0, \forall t = 1, 2, \dots, T$, which statement is true under sample size $T \to \infty$. (A) \( \hat{\beta} \) is consistent, but we cannot judge whether \( \hat{\beta} \) is efficiency (B) \( \hat{\beta} \) is unbiased and efficiency (C) \( \hat{\beta} \) is consistent and efficiency (D) \( \hat{\beta} \) is, but we cannot judge whether \( \hat{\beta} \) is efficiency (E) \( \hat{\beta} \) is unbiased and consistent.

4. Consider the simple regression $y_i = \alpha + \beta x_i + \varepsilon_i$And suppose population parameter $\beta = 2$ and least square estimator $\hat{\beta} = 2.3$. Now consider the regression $(x_i - y_i) = \alpha^* + \beta^* x_i + u_i.$What is the value of \( \hat{\beta} \)? (A) 1 (B)-1 (C)-1.3 (D)-0.3 (E) 0.3

62. In the realm of microbiology, bacteriophages, or phages, play a pivotal role in a specialized biomedical application known as phage therapy. Bacteriophages are viruses that infect and replicate within bacteria, and their unique ability to target specific bacterial strains makes them valuable tools for combating bacterial infections. Phage therapy involves utilizing these viruses to treat bacterial infections in a highly targeted manner, offering an alternative to traditional antibiotics. This specialized biomedical intervention has gained renewed interest as researchers explore personalized medicine, tailoring bacteriophages to individual patients based on the specific bacterial strains causing infections. The potential of phage therapy lies in its specificity and ability to evolve alongside bacteria, presenting a promising avenue in the ongoing battle against antibiotic-resistant pathogens. Which of the following statements best explains why doctors are increasingly interested in phage therapy? (A) Phage therapy is a valuable tool for combatting bacterial infections. (B) It is based in microbiology and makes use of bacteriophages. (C) It is the only way to combat illnesses caused by antibiotic-resistant pathogens. (D) Phage therapy can be personalized to address the needs of individual patients, making it a potential solution for unique or difficult-to-fight infections.

39. 一位清代學者指出：「地氣之盛衰，久則必變。唐開元、天寶間，地氣自西北轉東北之變局也。」我們應如何理解這個說法？(A)以「地氣」流動的觀念來解釋歷史，有違科學精神，此說不足採信(B)「地氣」是當時人對政治形勢變動的一種看法，此說內容值得參考(C)「地氣」是指農業生產的能力，「西北轉東北」是指其變動的方向(D)「開元、天寶間」的變局，安史集團攻擊長安可視為一項重要指標(E)唐以後首都從長安東移開封，再北移北京，可以說明地氣流動之說
